Question

what is modulus of rigidity

Answer 1

It's
Shear stress÷Shear strain...
It's dimensions are same as that of pressure

Answer 2

Shear Modulus (Modulus of Rigidity) is the elasticity coefficient for shearing or torsion force. Sponsored Links. Modulus of Rigidity - G - (Shear Modulus) is the coefficient of elasticity for a shearing force. It is defined as. "the ratio of shear stress to the displacement per unit sample length (shear strain)"
