a twisting force
a collar or neck chain, usually twisted, especially as worn by ancient barbaric nations, as the Gauls, Germans, and Britons
that which tends to produce torsion; a couple of forces
a turning or twisting; tendency to turn, or cause to turn, about an axis
Torque, moment or moment of force, is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist to an object. Mathematically, torque is defined as the cross product of the lever-arm distance and force, which tends to produce rotation. Loosely speaking, torque is a measure of the turning force on an object such as a bolt or a flywheel. For example, pushing or pulling the handle of a wrench connected to a nut or bolt produces a torque that loosens or tightens the nut or bolt. The symbol for torque is typically τ, the Greek letter tau. When it is called moment, it is commonly denoted M. 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. In symbols: where The length of the lever arm is particularly important; choosing this length appropriately lies behind the operation of levers, pulleys, gears, and most other simple machines involving a mechanical advantage. The SI unit for torque is the newton metre. For more on the units of torque, see below.
Chambers 20th Century Dictionary
tork, n. a twisting force: a necklace of metal rings interlaced.—adjs. Tor′quate, -d, collared; Torqued′, twisted. [L. torques—torquēre, to twist.]
U.S. National Library of Medicine
The rotational force about an axis that is equal to the product of a force times the distance from the axis where the force is applied.
The Standard Electrical Dictionary
A force tending to produce torsion around an axis. An example is the pulling or turning moment of an armature of an electric motor upon its shaft. It is often expressed as pounds of pull excited at the end of a lever arm one foot long. The expression is due to Prof. James Thompson, then of the University of Glasgow. "Just as the Newtonian definition of force is that which produces or tends to produce motion (along a line), so torque may be defined as that which produces or tends to produce torsion (around an axis). It is better to use a term which treats this action as a single definite entity than to use terms like 'couple' and 'moment,' which suggest more complex ideas." (S. P. Thompson.) A force, acting with radius r gives a torque equal to f X r ; f and r may be expressed in any units. S. P. Thompson gives the following equivalents : To reduce dyne-centimeters to gram centimeters, divide by 981 dyne-centimeters to meter-kilograms divide by 981E5 dyne-centimeter, to pound-feet divide by 13.56E6 pound-feet to meter-kilograms divide by 7.23 In each of these compound units the first unit is the force and the second unit is the radius or lever arm of the torque. Synonyms--Turning Moment--Moment of Couple--Axial Couple--Angular Force--Axial Force.

Sample Sentences & Example Usage
If we have a moving mass in front, that creates also a disturbance in the legs. So what we're developing is algorithms that can take into account that external disturbance from the payload or from the arm. And then servo the legs, control the legs in a way to compensate for these disturbances. And we've managed to do this very well; there's an example where we moved the arm left and right relatively fast, and if we don't use the smart controller the robot moves a lot. But if we turn on the smart controller, the torque and forces in the cylinders and joints are optimized so that the robot is relatively firm and rejects all these external disturbances.
Here's the interesting conversation between the Police Officer and one Indian Engineer who had gone to the police station to report his missing wife.: 'Officer, looks like I have lost my wife. She had gone to the mall yesterday for shopping and has not come home yet.' Okay, what's her height?' 'I've never noticed...maybe 4 to 5 feet?' 'Is she thin?' 'Not thin...may be healthy' 'Color of her eyes?' 'Not sure....maybe black?' 'Color of her hair?' 'Not sure. It keeps on changing.' 'What was she wearing?' 'Maybe Saree or Jeans....or Salwar Kameez?' 'Was she driving a car?' 'Yes!' 'Good! Then tell me the details like plate number, make, model and color of your car.' 'Officer, she has taken my favorite The BMW M135i, which is the top-of-the-range version of the BMW 1 Series. Color is Steel Grey and Plate number SRI 420. My beautiful BMW...she is such a distinctively dynamic vehicle produced by the BMW M GmbH. She's positioned between the most powerful BMW series production models and thoroughbred BMW M vehicles with noticeably higher performance than the previously most powerful engines of any BMW series and have M-specific characteristics in terms of suspension setting and visual appearance, though without any limitations in terms of suitability for everyday use. The heart of my new BMW M135i is her straight six-cylinder gasoline engine with Twin Scroll Turbo technology, Valvetronic, Double VANOS and High Precision Injection. She delivers 235 kW/320 hp and a maximum torque of 450 Nm, power transfer being enabled by her six-speed manual transmission fitted as standard. I know that my BMW M135i sprints from 0 to 100 km/h in just 5.1 seconds (and when automatic, it's 4.9 seconds) to reach a top speed of 250 km/h – that's because that's the top limit permitted by the vehicle's electronic speed control system. Her average fuel consumption in the EU test cycle was found to be 8.0 liters/100 km, and the CO2 emissions level was 188 grams per kilometer. The exclusive power train also features a customized cooling system, M performance control and engine sound tuning, plus a newly developed six-speed manual transmission with dry sump lubrication. She also has a dynamic eight-speed automatic sports transmission with gearshift paddles integrated in the steering wheel included as an option. Please find her as soon as you can. I miss her so much.' ' Wow! That really helps. Your details are awesome, and your memory is absolutely amazing. Please stop crying. We'll search for your car right away, and find her asap.... and maybe we'll find your wife as well.' The End.
