Torsion balance

Torsion balance
Torsion Tor"sion, n. [F., fr. LL. torsio, fr. L. torquere, tortum, to twist. See {Torture}.] 1. The act of turning or twisting, or the state of being twisted; the twisting or wrenching of a body by the exertion of a lateral force tending to turn one end or part of it about a longitudinal axis, while the other is held fast or turned in the opposite direction. [1913 Webster]

2. (Mech.) That force with which a thread, wire, or rod of any material, returns, or tends to return, to a state of rest after it has been twisted; torsibility. [1913 Webster]

{Angle of torsion} (of a curve) (Geom.), the indefinitely small angle between two consecutive osculating planes of a curve of double curvature.

{Moment of torsion} (Mech.) the moment of a pair of equal and opposite couples which tend to twist a body.

{Torsion balance} (Physics.), an instrument for estimating very minute forces, as electric or magnetic attractions and repulsions, by the torsion of a very slender wire or fiber having at its lower extremity a horizontal bar or needle, upon which the forces act.

{Torsion scale}, a scale for weighing in which the fulcra of the levers or beams are strained wires or strips acting by torsion. [1913 Webster]
