torsion, n 1. , motion or state of torque in which one end of an anatomical component is twisted about its longitudinal axis as the opposite end is either immobile or moves in the opposite direction.
Torque, moment, or moment of force (see the terminology below) 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 vector and the force vector, which tends to produce rotation.ust as a force is a push or a pull, a torque can be thought of as a twist to an object.
