The modulus of rigidity is the elastic coefficient when a shear force is applied resulting in lateral deformation. It gives us a measure of how rigid a body is. The table given below briefs everything you need to know about rigidity modulus. Example of Modulus Of Rigidity

Torsional rigidity is also defined as the torque required to produce a unit radian angle of twist per unit length of the shaft. The term torsional rigidity is expressed as, Torsional rigidity = G x J As GJ = T L θ T L θ ——– (∵ Torsional equation T J T J = Gθ L G θ L) Thus the equation of torsional rigidity can also be written as,
