71Torsion testiculaire — Pour les articles homonymes, voir Torsion (homonymie). La torsion testiculaire désigne la torsion du cordon spermatique, qui relie l un des testicules au reste du tractus génital. Ce cordon contenant notamment les artères vascularisant le… …
72Torsión (desambiguación) — La palabra torsión puede hacer referencia a: En matemáticas: La torsión de una conexión. La torsión de una curva. En ingeniería mecánica y estructural: El péndulo de torsión. El resorte de torsión. El coeficiente de torsión. La barra de torsión.… …
73Torsion-free abelian groups of rank 1 — Infinitely generated abelian groups have very complex structure and are far less well understood than finitely generated abelian groups. Even torsion free abelian groups are vastly more varied in their characteristics than vector spaces. Torsion… …
74Torsion (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… …
75torsion 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 …
76Torsión en planta — Se denomina torsión en planta al esfuerzo de torsión que sufre la estructura portante de un edificio cuando es sometida a grandes esfuerzos horizontales. Este efecto es particularmente significativo en los terremotos. La torsión en planta aparece …
77Torsion-free — In mathematics, the term torsion free may refer to several unrelated notions: * In abstract algebra, a group is torsion free if the only element of finite order is the identity. * In differential geometry, an affine connection is torsion free if… …
78Torsion dystonia — A form of dystonia known as early onset torsion dystonia (also called idiopathic or generalized torsion dystonia) that begins in childhood around the age of 12. Symptoms typically start in one part of the body, usually in an arm or leg, and… …
79Torsion box — A torsion box consists of two skins applied to a core material, usually a grid or framework of some kind. The torsion box functions as a beam, but is considerably lighter than a solid beam of the same size without losing much strength. Torsion… …
80torsion bar — a metal bar having elasticity when subjected to torsion: used as a spring in various machines and in automobile suspensions. [1945 50] * * * Rod or bar that resists twisting (see torque) and has a strong tendency to return to its original… …
