Torsion constant — The torsion constant is a geometrical property of a beam s cross section which determines the relationship between angle of twist and applied torque.For a beam of uniform cross section along its length: heta = frac{TL}{JG} heta is the angle of… … Wikipedia
Torsion (mechanics) — In solid mechanics, torsion is the twisting of an object due to an applied torque. In circular sections, the resultant shearing stress is perpendicular to the radius.For solid or hollow shafts of uniform circular cross section and constant wall… … Wikipedia
Torsion spring — A mousetrap powered by a helical torsion spring A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted. The amount of force (actually torque) it exerts… … Wikipedia
Torsion of a curve — In the elementary differential geometry of curves in three dimensions, the torsion of a curve measures how sharply it is twisting. Taken together,the curvature and the torsion of a space curve are analogous to the curvature of a plane curve. For… … Wikipedia
Torsion tensor — In differential geometry, the notion of torsion is a manner of characterizing a twist or screw of a moving frame around a curve. The torsion of a curve, as it appears in the Frenet Serret formulas, for instance, quantifies the twist of a curve… … Wikipedia

torsion balance — an instrument for measuring small forces, as electric attraction or repulsion, by determining the amount of torsion or twisting they cause in a slender wire or filament. [1820 30] * * * Device used to measure the gravitational acceleration at the … Universalium
Constant-velocity joint — Rzeppa six ball CV joint Constant velocity joints (aka homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly… … Wikipedia
Gravitational constant — The gravitational constant G is a key quantity in Newton s law of universal gravitation. The gravitational constant, denoted G, is an empirical physical constant involved in the calculation of the gravitational attraction between objects with… … Wikipedia
