torsion

Coulomb was the maker of the first instrument for measuring a current, which was known as the torsion balance.

Penaud's machine, relying only on india rubber under torsion, flies for some fifty yards.

On the other hand, the law of torsion could hardly be quite so simple, at all events, to the second order of approximations.

Its free motion differs entirely from that given it by torsion or stress.

The old freighter swung a great circle, its torsion jets blasting desperately in an effort to keep it on an even keel.
