torsions

Forces causing rotation

Torsions is the plural of torsion, the twisting of an object by forces applied at opposite ends in opposite directions.

In mechanics, torsion measures the stress or strain produced by such twisting: The engineer calculated the torsions acting on the drive shaft.

In medicine, torsion describes abnormal twisting of an organ, as in testicular torsion.

In mathematics, torsion refers to the twisting of a curve in three-dimensional space.
