**KEY TOPICS **

**[1] The basic definition of torque in physics is a turning or twisting force. [2]**

*Using a simple definition, torque is equivalent to force times distance, where a clockwise torque or twist is usually positive and a counter-clockwise torque is usually negative.*The definition of torque states that one or both of the angular velocity or the moment of inertia of an object are changing. [3]

** In the same way that one ton is a large amount of weight (by definition, 2000 pounds), one horsepower is a large amount of power.** [4] The definition of one horsepower is 33,000 foot-pounds per minute. [4]

** The same principles regarding the conditions that influence the ability of similar forces to generate rotary motion also apply to the definition of actuator torque.** [5] We now have the ability to configure the torque curve in the engine definition. [6]

** The constant below (in foot pounds per minute) changes with the definition of the horsepower; for example, using metric horsepower, it becomes approximately 32,550.** [3] By definition, linear distance linear speed time radius angular speed time. [3]

** Of course, along with the good comes the bad – I now have to spend a crap load of time updating all my engine definitions :/ heh.** [6] We can now define the idle speed for an engine definition, as well as the neutral gear RPM limit for those engines which have this feature (ISX). [6] Unfortunately, this same curve is applied to all default engines, however we can now define the curve for any individual engine definition. [6]

This option is only available for the force motor definition. [7] By definition, if we calculate work as a vector force, exerted in a line witch is straight. [8]

**POSSIBLY USEFUL **

**[1] The one of the major difference between power and torque is that the power is the amount of work done by an object whereas the torque is the tendency of the force to rotate the object in a particular direction. [9] Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis of rotation or point of support on which a lever turns in rotating the object. [2] The magnitude of torque depends on the applied force, the length of the lever arm connecting the axis or rotation of the lever to the point of force application, and the angle between the force direction and the lever arm. [2] TORQUE is defined as a FORCE around a given point, applied at a RADIUS from that point. [4] NOTE that IF the crank-arm in the sketch was twice as long (i.e. the handle was located 24″ from the center of the shaft), the same 100 pound force applied to the handle would produce 200 lb-ft of torque (100 pounds times 2 feet). [4] The power is defined as the ratio of the energy consumed with respect to time, whereas the torque is the product of the force and distance. [9] The power is the amount of energy consumed per unit of time, whereas the torque is the measure of energy whose effect can rotate the object. [9] The unit of power is a joule per second, whereas the unit of torque is equivalent to the joule. [9]**

*Reaction torque is the turning force, or moment, imposed on the stationary portion of a device by the rotating portion as power is delivered or absorbed.*A dyne meter (dynm) is a decimal multiple of the CGS unit of torque (also called “moment” or “moment of force”), dyne centimeter. [2] A newton centimeter (Ncm) is a decimal fraction of a newton meter, which is a derived SI unit of torque (also called “moment” or “moment of force”). [2] A gram-force centimeter (gfcm) is a metric unit of torque (also called “moment” or “moment of force”). [2] A kilogram-force meter (kgfm) is a metric unit of torque (also called “moment” or “moment of force”). [2] A gram-force millimeter (gfmm) is a metric unit of torque (also called “moment” or “moment of force”). [2] A pound-force foot (lbfft) is a unit of torque (also called “moment” or “moment of force”) in the U.S. Customary Units and British Imperial Units. [2]

The moment of a force (or the torque produced by a force) is a measure of the turning effect of the force. [10] The torque twisted the object in a direction opposite to which the force is applied to it. [9] The torque is induced when the force is applied on an object or body. [9] If a force is used to begin to rotate an object, or to stop an object from rotating, a torque is made. [2] The torque is the measure of the circular force whose effect can rotate the object. [9] Similar to force being described as push or pull, torque can be described as a twist to an object. [1] Torque is the turning force through a radius – with the units Nm in the SI-system and the units lb ft in the imperial system. [11] Examples of torque For tightening or opening the cap of the bottle, we have applied force through the hand. [9] Mathematically, torque is defined as the product of force and the lever-arm distance, which tends to produce rotation. [2] We conclude that the turning effect or torque of a force depends on the magnitude of the force and the perpendicular distance between the line of action of the force and the pivot (the hinge of the door in the case above). [10]

An engine produces POWER by providing a ROTATING SHAFT which can exert a given amount of TORQUE on a load at a given RPM. [4] The dynamometer control system causes the absorber to exactly match the amount of TORQUE the engine is producing at that instant, then measures that TORQUE and the RPM of the engine shaft, and from those two measurements, it calculates observed power. [4] The RPM band within which the engine produces its peak torque is limited. [4] [xyz-ihs snippet=”Amazon-Affiliate-Native-Ads”] Typically, the torque peak will occur at a substantially lower RPM than the power peak. [4] POWER (the rate of doing WORK) is dependent on TORQUE and RPM. [4] The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. [11] The Pull-up Torque is the minimum torque developed by an electrical motor when it runs from zero to full-load speed (before it reaches the break-down torque point). [11] When a motor starts and begins to accelerate the torque in general will decrease until it reach a low point at a certain speed – the pull-up torque – before the torque increases until it reach the highest torque at a higher speed – the break-down torque – point. [11] This is the maximum torque a motor can develop at any point on its speed-torque curve. [12] The torque developed by an asynchronous induction motor varies when the motor accelerates from zero to maximum operating speed. [11] The Locked Rotor Torque or Starting Torque is the torque an electrical motor develops when starting at zero speed. [11] To some, this means the total torque exerted by the motor as it comes up to speed. [12] To others, it means the average torque a motor develops while accelerating to full speed. [12]

It’s sometimes been used to denote the average difference between motor torque and load torque during acceleration. [12] If a connected load demands more torque than that, the motor will stall. [12] If you are working with nonconditioned sensors, you must consider several signal conditioning elementsto create an effective bridge-based load and torque measurement system. [1] To learn how to compensate for these errors and review other hardware considerations for bridge-based load and torque measurements, download the Engineer’s Guide to Accurate Sensor Measurements. [1] Extraneous torque and moments can increase the combined stress, which accelerates fatigue and affects sensor accuracy and performance. [1] These sensors are commonly used to measure torque of a back-and-forth agitating type motion. [1] Reduced Voltage Soft Starters are used to limit the start current reducing the Locked Rotor Torque or Starting Torque and are common in applications which is hard to start or must be handled with care – like positive displacement pumps, cranes, elevators and similar. [11] A high Starting Torque is more important for application or machines hard to start – like positive displacement pumps, cranes etc. A lower Starting Torque can be accepted for centrifugal fans or pumps where the start load is low or close to zero. [11] The pull-up torque may be critical for applications that needs power to go through some temporary barriers achieving working conditions. [11] By evaluating the torque requirements against realistic BMEP values you can determine the reasonableness of the target power curve. [4] Note how that causes the green power line to increase well beyond the torque peak. [4] The power is a scalar quantity (i.e. Directionless) whereas the torque is a vector quantity. [9] The SI unit of power is the watt, whereas the SI unit of torque is Newton-meter. [9] The power is represented by the letter P whereas the torque is represented by the Greek alphabet ? (tau). [9] The question is usually asked in a tone which strongly suggests that these “experts” believe power and torque are somehow mutually exclusive. [4]

The point to be taken from those numbers is that a given amount of horsepower can be made from an infinite number of combinations of torque and RPM. [4] The amount of TORQUE the engine can exert usually varies with RPM. [4] TORQUE and RPM are the MEASURED quantities of engine output. [4] At any RPM below 5252, the value of torque is greater than the value of HP; Above 5252 RPM, the value of torque is less than the value of HP. [4] This value is sometimes called either “stall torque” or “pullout torque.” [12] There’s an added complexity compared to the torque situation, because when a motor is first energized it draws a short-time transient current that is much higher than the locked-rotor value. [12] The following examples illustrate several different values of TORQUE which produce 300 HP. [4] Note that the unit of TORQUE is one pound-foot (often misstated), while the unit of WORK is one foot-pound. [4] Other non-SI units of torque include meter-kilograms-force. [2]

Because the shaft is fixed to the wall, the shaft does not turn, but there is a torque of 100 pound-feet (100 pounds times 1 foot) applied to the shaft. [4] For tightening or loosing the nut through spanner and for twisting the steering of the car torque is applied. [9]

Engine effects and aerodynamic phenomena Recreational Aviation Australia Ground School article on “prop wash,” prop torque, gyro precession, p-factor and other similar factors affecting taildraggers. [13] Torque effect is the influence of engine torque on aircraft movement and control. [13]

If the load source is held rigid while the drive source is trying to rotate, the torque is sensed. [1] Any load other than torque, such as axial, radial, or bending, is considered extraneous and should be determined beforehand. [1] We can say the torque is the load carrying capacity of the vehicles. [9]

Some people consider this to mean the torque a motor develops at the instant it’s energized. [12] NEMA (National Electrical Manufacturers Association) have classified electrical motors in four different designs where torques and starting-load inertia are important criteria. [11]

It is important to understand that torque is a movement about the roll axis. [13] In more advanced work you will discover the idea of the vector nature of torque. [10] On aircraft with contrarotating propellers (propellers that rotate in opposite directions) the torque from the two propellers cancel each other out, so that no compensation is needed. [13] To select the correct capacity, determine the minimum and maximum torque you expect. [1] The recognized SI unit of measure for torque is Newton-meters (Nm). [1] The SI unit of torque is newton-meter and newton-meter is equivalent to joule. [9]

One kilogram-force meter is equal to the torque resulting from a force of one kilogram-force applied perpendicularly to a one meter long moment arm. [2] One dyne centimeter is equal to the torque resulting from a force of one dyne applied perpendicularly to a one centimeter long moment arm. [2] One newton meter is equal to the torque resulting from a force of one newton applied perpendicularly to a one meter long moment arm. [2] One pound-force foot is equal to the torque resulting from a force of one pound-force applied perpendicularly to a one foot long moment arm. [2] One kilogram-force millimeter is equal to the torque resulting from a force of one kilogram-force applied perpendicularly to a one millimeter long moment arm. [2] In order to design an engine for a particular application, it is helpful to plot out the optimal power curve for that specific application, then from that design information, determine the torque curve which is required to produce the desired power curve. [4]

The solid lines show the power produced by the torque curves of the same color. [4] The electrical power is measured through the energy meter or multimeter whereas the torque is measured through torque sensor or torque meter. [9] For rotary torque sensors, you need to understand how long the torque sensor will be rotating and at what speed to determine the RPM. [1] The three dashed lines represent three different torque curves, each having exactly the same shape and torque values, but with the peak torque values located at different RPM values. [4] You can tailor an engine to have a high peak torque with a very narrow band, or a lower peak torque value over a wider band. [4] Alterations intended to broaden the torque peak will inevitable reduce the peak torque value, but the desirability of a given change is determined by the application. [4]

Rotating torque sensors are similar in design and application to reaction torque sensors except that the torque sensor is installed in line with the device under test. [1] Load and torque sensors can be either conditioned or nonconditioned. [1] Similar to your load cell selections, your torque sensor selections primarily depend on your capacity needs and physical or environmental requirements. [1]

Reaction torque sensors are restrained so they cannot rotate 360 deg without the cable wrapping up because the housing or cover is fixed to the sensor element. [1] Rotary slip ring torque sensors can be used to measure startup, running, and stall torque levels. [1] Since the shaft of a torque sensor is rotating 360 deg, these sensors must have a way to transfer the signals from the rotational element to a stationary surface. [1]

The reason is that, in general, the torque curve does not drop off (%-wise) as rapidly as the RPM is increasing (%-wise). [4]

Moment is the general term used for the tendency of one or more applied forces to rotate an object about an axis, but not necessarily to change the angular momentum of the object (the concept which is called torque in physics). [3] Similarly with any force couple on an object that has no change to its angular momentum, such moment is also not called a torque. [3] By contrast, a lateral force on a beam produces a moment (called a bending moment ), but since the angular momentum of the beam is not changing, this bending moment is not called a torque. [3] A rotational force applied to a shaft causing acceleration, such as a drill bit accelerating from rest, results in a moment called a torque. [3] The Principle of Moments, also known as Varignon’s theorem (not to be confused with the geometrical theorem of the same name) states that the sum of torques due to several forces applied to a single point is equal to the torque due to the sum (resultant) of the forces. [3] If the force is perpendicular to the displacement vector r, the moment arm will be equal to the distance to the centre, and torque will be a maximum for the given force. [3] Mathematically, torque is defined as the cross product of the vector by which the force’s application point is offset relative to the fixed suspension point ( distance vector ) and the force vector, which tends to produce rotational motion. [3] The magnitude of torque depends on three quantities: the force applied, the length of the lever arm connecting the axis to the point of force application, and the angle between the force vector and the lever arm. [3] The torque vector points along the axis of the rotation that the force vector (starting from rest) would initiate. [3]

For an object to be in static equilibrium, not only must the sum of the forces be zero, but also the sum of the torques (moments) about any point. [3] Relationship between force F, torque ?, linear momentum p, and angular momentum L in a system which has rotation constrained in one plane only (forces and moments due to gravity and friction not considered). [3] Note that the power injected by the torque depends only on the instantaneous angular speed – not on whether the angular speed increases, decreases, or remains constant while the torque is being applied (this is equivalent to the linear case where the power injected by a force depends only on the instantaneous speed – not on the resulting acceleration, if any). [3] When a force F is applied to the particle, only the perpendicular component F ? produces a torque. [3] A force applied at a right angle to a lever multiplied by its distance from the lever’s fulcrum (the length of the lever arm ) is its torque. [3] Since torque is simply a force applied through some distance, we can easily convert torque into a driving or propulsive force and then calculate acceleration. [14] Torque is defined as “a force applied at a given distance from the center of rotation that causes rotation”. [15] The quantity torque may be thought of as the cross product of force and distance, suggesting the unit newton metre, or it may be thought of as energy per angle, suggesting the unit joule per radian.” [3] At the outset of this section, we noted that torque was a twisting couple, which means that it has units of force times distance, or. [16] Torque has dimension force times distance, symbolically L 2 M T ?2. [3] It is dimensionally equivalent to a force of one newton acting over a distance of one metre, but it is not used for torque. [3] A force of three newtons applied two metres from the fulcrum, for example, exerts the same torque as a force of one newton applied six metres from the fulcrum. [3] The torque (and corresponding force) required to pull the object is equal to the frictional force between the pallet and concrete slab. [14] Loosely speaking, torque is a measure of the turning force on an object such as a bolt or a flywheel. [3] Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. [3] If a person places a force of 10N at the terminal end of a wrench that is 0.5m long (or a force of 10N exactly 0.5m from the twist point of a wrench of any length), the torque will be 5N.m – assuming that the person moves the wrench by applying force in the plane of movement and perpendicular to the wrench. [3] The direction of the torque can be determined by using the right hand grip rule : if the fingers of the right hand are curled from the direction of the lever arm to the direction of the force, then the thumb points in the direction of the torque. [3] When the net force on the system is zero, the torque measured from any point in space is the same. [3] Any force directed parallel to the particle’s position vector does not produce a torque. [3] Pushing or pulling the handle of a wrench connected to a nut or bolt produces a torque (turning force) that loosens or tightens the nut or bolt. [3] If you place the transmission in drive and accelerate from a standstill at wide open throttle, the engine load will be high and it will eventually produce peak torque followed by peak horsepower at the corresponding engine speeds. [14] Peak horsepower/torque are only realized under wide open throttle driving conditions, whereas the actual engine horsepower and torque being produced under given circumstances depends on the total load applied to the engine. [14] Load is also an important principle – if you were to rev an engine at full throttle with the transmission in neutral, it would produce very little torque as the only load applied to the engine would result from the mass of the rotating assembly. [14] Steam engines and electric motors tend to produce maximum torque close to zero rpm, with the torque diminishing as rotational speed rises (due to increasing friction and other constraints). [3] Internal-combustion engines produce useful torque only over a limited range of rotational speeds (typically from around 1,000-6,000 rpm for a small car). [3]

The horizontal axis is the speed (in rpm ) that the crankshaft is turning, and the vertical axis is the torque (in newton metres ) that the engine is capable of providing at that speed. [3] If you wanted to know the minimum input for an application and were given engine torque at a governed speed, you would have to calculate the horsepower at that engine speed in order to declare whether or not you would be able to obtain your desired output power. [14] Larger head handpieces typically have much higher torque and somewhat lower speed (rpm) but higher overall cutting power. [15] Smaller head handpieces tend to have higher speed (rpm) and lower torque yet can still generate good cutting power while delivering better accessibility and visibility. [15] For metric SI units, power is watts, torque is newton metres and angular speed is radians per second (not rpm and not revolutions per second). [3] Some people (e.g., American automotive engineers) use horsepower (imperial mechanical) for power, foot-pounds (lbf?ft) for torque and rpm for rotational speed. [3] Torque is part of the basic specification of an engine : the power output of an engine is expressed as its torque multiplied by its rotational speed of the axis. [3] If Imperial units are used, and if torque is in pounds-force feet and rotational speed in revolutions per minute, the above equation gives power in foot pounds-force per minute. [3] We also used a method of dimensional analysis to determine the power generated by a transmission shaft (i.e. a rod) that spins with a given frequency under an applied torque. [16] A conversion factor may be necessary when using different units of power or torque. [3] By inspection, to generate power with a torque, we need something that occurs with a given frequency f, since frequency has the units of Hertz or. [16] The dimensional equivalence of these units, of course, is not simply a coincidence: a torque of 1N?m applied through a full revolution will require an energy of exactly 2? joules. [3] There is a torque applied to the bolt at this point of time equal to the your weight x the length of the wrench. [14] A torque can be applied at a point with zero rotational movement. [14] I Moment of inertia about the point which the torque is written (either instantaneous axis of rotation or center of mass only). [3] This article follows the U.S. physics terminology by calling all moments by the term torque, whether or not they cause the angular momentum of an object to change. [3] The torque caused by the two opposing forces F g and ? F g causes a change in the angular momentum L in the direction of that torque. [3] It follows from the properties of the cross product that the torque vector is perpendicular to both the position and force vectors. [3] For a two-dimensional situation with horizontal and vertical forces, the sum of the forces requirement is two equations: ? H 0 and ? V 0, and the torque a third equation: ? ? 0. [3]

Torque and horsepower are of equal importance and inherent value in understanding the performance characteristics of internal combustion engines. [14] Diesel owners tend to pay particular attention to the torque ratings of an engine more so than the peak horsepower an engine can produce. [14] Peak horsepower and torque ratings are often used to identify performance characteristics in internal combustion engines. [14] It’s important to realize that manufacturer’s advertise peak engine horsepower and torque. [14] In this article, we’ll examine the relationship, in addition to the differences between horsepower and torque and how the two engine ratings apply to various situations. [14] An engine producing greater torque will have the greater ability to overcome large loads from a standstill – accelerating a heavy trailer up to speed from a dead stop, for example. [14] Torque can be described as the tendency of an object to overcome an applied load. [14] Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section. [16] Torque – Torque is the measure of an objects tendency to rotate about a point. [14] As a torque is applied to the rod, it will twist, and the hour hand will rotate clockwise to a new position (say, 2 o’clock). [16] When a torque is applied to the structure, it will twist along the long axis of the rod, and its cross section remains circular. [16] For the application of cutting tooth with a highspeed handpiece, the torque of the handpiece would determine how much pressure could be applied to the bur before the handpiece stalled during cutting. [15] For the sake of practicality, the application dictates whether torque or horsepower is intuitively more significant and/or purposeful to an individual. [14] “Horsepower and Torque” An article showing how power, torque, and gearing affect a vehicle’s performance. [3] The product of the two (speed x torque) determines its power and how fast tooth material is removed. [15] The input power provided by the cyclist is equal to the product of cadence (i.e. the number of pedal revolutions per minute) and the torque on spindle of the bicycle’s crankset. [3] Clinically, power is clearly more important than torque and leading handpiece manufacturers typically publish the maximum cutting power their handpieces deliver at maximum allowable air pressure. [15] In the following formulas, P is power, ? is torque, and ? is rotational speed. [3] By using a larger rear gear, or by switching to a lower gear in multi-speed bicycles, angular speed of the road wheels is decreased while the torque is increased, product of which (i.e. power) does not change. [3] Algebraically, the equation may be rearranged to compute torque for a given angular speed and power output. [3] The takeaway from this example is that torque itself is intuitively irrelevant in meeting the needs of our fictitious generator if a minimum power is not produced. [14] Often dentists and even some handpiece suppliers use torque and power interchangeably. [15]

Energy and torque are entirely different concepts, so the practice of using different unit names (i.e., reserving newton metres for torque and using only joules for energy) helps avoid mistakes and misunderstandings. [3] In the case of torque, the unit is assigned to a vector, whereas for energy, it is assigned to a scalar. [3] Torque is sometimes listed with units that do not make dimensional sense, such as the gram-centimeter. [3]

This constant is the reason that horsepower and torque graphs always cross paths at 5,252 rpm. [14] The concept is understandably confusing at this point, as you may be thinking that horsepower has no relationship to acceleration and torque alone is responsible. [14] The torque on a current-carrying loop in a uniform magnetic field is the same regardless of your point of reference. [3] If body is in translatory equilibrium then the torque equation is the same about all points in the plane of motion. [3]

This final equation allows us to split up torques applied to different parts of the same structure. [16] When no torque is applied, the hour hand sits at 12 o’clock. [16] When we apply a torque equal to the minimum required value, the pallet begins to move towards the winch. [14] Therefore, torque on a particle is equal to the first derivative of its angular momentum with respect to time. [3] Torque is defined mathematically as the rate of change of angular momentum of an object. [3] To put it simply, applying a torque to an object will make it spin. [17]

A highspeed handpiece needs both rotational speed (rpm) and torque. [15] Depending on the gear ratio of the bicycle, a (torque, rpm) input pair is converted to a (torque, rpm) output pair. [3]

The resulting torque vector direction is determined by the right-hand rule. [3] If tfeedforward is used, it is the feedforward torque vector. [18] In Imperial units, ” pound-force-feet ” (lbf?ft), “foot-pounds-force”, “inch-pounds-force”, “ounce-force- inches ” (ozf?in) are used, and other non-SI units of torque includes “metre- kilograms-force “. [3] In this example, horsepower is intuitively meaningless to the situation – we’re really only concerned with producing enough torque to keep the pallet moving. [14] This brings up an important distinction between horsepower and torque. [14] A dynamometer actually measures torque and calculates horsepower using the formula above. [14] An advantageous method of approach is to understand the relationship between horsepower and torque. [14] The differences between horsepower and torque are not nearly as importance as the relationship between the two concepts. [14] The concept of torque, also called moment or couple, originated with the studies of Archimedes on levers. [3] The given torque at the input gets multiplied as per the reduction ratio and transmitted to the output, thereby achieving greater torque, but with reduced rotational speed. [3] Torque, which is measured about a fixed axis, is not a time dependent variable. [14] A torque is not necessarily limited to rotation around a fixed axis, however. [3] This equation has the limitation that the torque equation describes the instantaneous axis of rotation or center of mass for any type of motion – whether pure translation, pure rotation, or mixed motion. [3]

If torque is allowed to act through a rotational distance, it is doing work. [3] If we apply a torque to the winch cable drum below this minimum value, nothing happens. [14] PID mode: the user controls the motor’s PID setpoints directly Torque control: the user controlls the motor torques directly. [18]

NOTE: To say that the lockup torque converter LOCKS the engine and transmission together isn’t completely accurate because slipping can still occur if the vehicle has a heavy enough load. [19] Positioned between the rear of the engine and the front of the transmission is the torque converter. [19] The torque converter is responsible for transmitting the engine’s torque and power to the transmission. [19] The cost to replace a failed transmission torque converter clutch solenoid is determined, in part, by the vehicle year, make and model. [19] Replacing a transmission torque converter clutch solenoid can be done by most any auto repair shop, automobile dealership service center or you can do-it-yourself “DIY“. [19] Once it is determined that the transmission torque converter clutch solenoid is faulty, the solenoid must be replaced. [19] Below are costs for replacing the transmission torque converter clutch solenoid in four different vehicles. [19] A faulty torque converter clutch solenoid normally sets a Diagnostic Trouble Code (DTC), which causes the Check Engine Light to come on. [19] The symptoms are different a torque converter clutch solenoid that fails in the open position. [19] The fluid pressure that applies and releases the torque converter lockup clutch is controlled by the torque converter clutch solenoid. [19] With respect to drivability and performance, a malfunctioning torque converter clutch solenoid (one that fails in the closed position) may not be noticeable. [19]

A faulty Torque Converter Clutch (TCC) Solenoid A damaged transmission wiring harness, loose connection or open circuit in the system A problem in the Transmission Control Module (TCM) or Powertrain Control Module (PCM), depending on the vehicle. [19]

The expression of this rotational or twisting force around an axis is also called torque, which is measured in units of force times distance from the axis of rotation. [8] This reaction is caused by the engine’s torque, which, although its output force is harnessed to drive the car forward along its own axis, exerts a rotational movement around the car’s axis. [5] Torque is a term used to define the extent to which a motive force twists an object around its own axis or a fulcrum point. [5] Theoretically the torque (here electro-magnetical torque) is equal to the multiplication of force with distance to the point of suspension. [20] If the screwdriver handle is well-designed and does not slip in the handyman’s hand, a large amount of torque is being generated and applied to the screw by the force applied to the screwdriver handle. [5] Torque, on the other hand, is best described as the result of the application of force to a wrench, which turns a bolt around its axis. [5] When you define this type of Force Motor, Force, or Torque, set Motion Direction options. [7] Use the Motor tab to define a servo motor, force motor, or force torque. [7] The same principle applies to an actuator with internal mechanism designs dictating how well the actuator motor translates its latent force into usable torque. [5] You can switch between a servo, a force motor, a force or a torque when you have a Mechanism Dynamics license. [7] A low torque rating will mean that the actuator will be able to maintain its output force over a very narrow load range. [5] If the wrench were 2 feet long, the same force would apply a torque of 20 lb-ft. [8] If you have a one foot-long wrench and you make her longer with a force of 10 pounds on the end of it then you apply a torque of 10 pound-feet (10 lb-ft). [8]

The standard I settled on was a 15.2 litre, 373kW (500hp) engine giving 2500 Nm peak torque at 1500 RPM. The function I used to derive a proportional torque for any given displacement vs hp rating was (approximately, I didn’t bother digging up my actual function). [6] Both counter and main shaft consists of gears of different diameters and teeth, which mesh with each other and form different gear ratios to vary the engine torque and speed. [21] The engine design is such that, it produces good amount of torque in middle ranges, whereas a vehicle needs sufficient torque during starting from rest or when it is running slowly and friction between the tire and road surface is high. [21] In this gear configuration, the engine is not able to develop much torque and, to efficiently climb the hill, a lower gear will have to be selected. [5] In simple terms, the more torque a device can generate, the more power it will be able to exert over a wider range of operational loads. [5] It helps to vary the torque and speed according to the load of the vehicle and helps the vehicle to move against friction. [21] Primary function of the gearbox is to vary the torque and speed and this is done by using gears of different teeth and diameters. [21]

The way I dealt with this was to reduce/increase rated torque output proportionally from a defined displacement vs rated power standard. [6] This torque is produced by the spring action and opposes the deflection torque so as the pointer can come to rest at the point where these two torques are equal (Electromagnetic torque control spring torque). [20] When the torques are balanced the moving coil will stopped and its angular deflection represent the amount of electrical current to be measured against a fixed reference, called a scale. [20] The moving coil instrument can only be used on D.C supply as the reversal of current produces reversal of torque on the coil. [20] A threaded fastener used for any assembly process requires proper torque control. [22]

The value of control torque depends on the mechanical design of spiral springs and strip suspensions. [20] The torque rating of the device will dictate what type of applications the actuator will realistically be able to handle. [5] The Micro Torque screwdriver is an externally adjustable torque tool that offers different setting options for applications that require more than one torque value. [22] Field service and maintenance fastening applications often require a tool that delivers both torque control and the flexibility to easily adjust to different torque values. [22] This makes informed choices critical when selecting devices for applications requiring high actuator torque values. [5]

High torque values are not always called for, so not all actuators develop the same torque outputs even though they may have similar power plants. [5]
