WebbTorsion simple. Cours RDM / A.U : 2012-2013 Cours résistance des matériaux 32 I. Introduction : Définition : Une poutre est sollicitée à la torsion simple si elle est soumise à deux couples de moments opposés portés par la ligne moyenne. La poutre est supposée à section circulaire constante et de poids négligé. Webb6 aug. 2014 · 1. Expt No: Date: TORSION TEST ON WIRES AIM: To determine the modulus of rigidity of material of steel wire. APPARATUS: Torsion wire, Wooden disc, Cylinders of known weight, Stopwatch & Screw gauge. PRINCIPLE: Whenever a filament is twisted (thread, string, wire etc) forces come into play that make it untwist. These are called …

As a rule of thumb: When brittle materials are subjected to torsion they fail in the plane, where tension is at its highest, i.e. at a 45° angle. Ductile materials on the other hand fail in the plane of maximum shear stress. … siemens fire alarm system manuals
