Twisting is another term for torsion, in which a body twists against each other around its longitudinal axis.
This deformation is triggered by a moment acting transverse to the longitudinal axis. Unlike the general term torsion, twisting is usually used in a more specific way. The term refers primarily to the reaction of fibers or wires to the torsional load.
Individual wires twist against each other and wind up in the form of a screw. This effect is used specifically in telecommunications technology, for example, to influence the electromagnetic properties of the material.
In technical mechanics, twisting is a measure of how much a bar subjected to torsion has twisted.
