torsion    
n. 扭转,转矩

扭转,转矩

torsion
n 1: a tortuous and twisted shape or position; "they built a
tree house in the tortuosities of its boughs"; "the acrobat
performed incredible contortions" [synonym: {tortuosity},
{tortuousness}, {torsion}, {contortion}, {crookedness}]
2: a twisting force [synonym: {torsion}, {torque}]

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]

  • Torsion (mechanics) - Wikipedia
    In the field of solid mechanics, torsion is the twisting of an object due to an applied torque [1][2] Torsion could be defined as strain [3][4] or angular deformation, [5] and is measured by the angle a chosen section is rotated from its equilibrium position [6]
  • What Is Torsion Force? The Mechanics of Twisting
    Torsion is the internal deformation or twisting that occurs within an object when an external rotational force, known as torque, is applied This differs significantly from simple linear forces, such as a direct push or pull, or bending

  • TORSION Definition Meaning - Merriam-Webster
    The meaning of TORSION is the twisting or wrenching of a body by the exertion of forces tending to turn one end or part about a longitudinal axis while the other is held fast or turned in the opposite direction; also : the state of being twisted
  • What is torsion and how does it affect structural components?
    Torsion is a type of mechanical force that causes an object to twist along its length due to a rotational force (torque) It occurs when opposite forces are applied at different points on a structure, leading to shear stress and angular deformation
