Spring Material Test (Modulus of Rigidity)
Modulus of rigidity is the measurement of the stiffness of spring material or its elastic ability. The modulus of rigidity of a spring material varies as a function of chemical composition, cold working, and degree of aging. Apparatus Required Spring ...
Torsion Pendulum Test on Metal Wire
Modulus of Rigidity is the coefficient of elasticity of wire for a shearing force. In simple words, rigidity modulus of a metal wire is a measurement of the capability of a material to resist deformation when external tangential (parallel to the surface) force ...
