torsion (Noun)
The act of turning or twisting, or the state of being twisted; the twisting or wrenching of a body by the exertion of a lateral force tending to turn one end or part of it about a longitudinal axis, while the other is held fast or turned in the opposite direction.
torsion (Noun)
That force with which a thread, wire, or rod of any material, returns, or tends to return, to a state of rest after it has been twisted; torsibility.

torsion
tor′shun, n. act of twisting or turning a body: the force with which a thread or wire tends to return when twisted, the kind of strain produced in a bar or wire when one end is kept fixed and the other is rotated about the axis: (surg.) a method of common application for the purpose of checking arterial hæmorrhage in certain cases, by twisting the cut end of the artery.—n. Torsibil′ity.—adj. Tor′sional, pertaining to, or resulting from, torsion.—n. Tor′sion-bal′ance, an instrument for measuring very minute forces by a delicate horizontal bar or needle, suspended by a very fine thread or wire.—adj. Tor′sive, twisted spirally. [L. torsio—torquēre, tortum, to twist.]

mechanics
In solid mechanics, torsion is the twisting of an object that is result of an applied torque. In circular sections, the resultant shearing stress is perpendicular to the radius.

"T" is the applied torque, "r" is the distance from the center of rotation, and "J" is the polar moment of inertia.
