In my view, the Christian religion is the most important and one of the first things in which all children, under a free government ought to be instructed... No truth is more evident to my mind than that the Christian religion must be the basis of any government intended to secure the rights and privileges of a free people. Preface to 1828 Dictionary

TOR'SION, n. [L. torsio, from torqueo, to twist.] The act of turning or twisting.
Torsion balance, an instrument for estimating very minute forces by the motion of an index attached to the ends of two fine wires,which twist around each other.
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.
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.
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. | ||||||||
