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.
Torsion. In solid mechanics, torsion is the twisting of an object due to an applied torque, therefore is expressed in NÂ·m or ftÂ·lbf. In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius.
