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.
