Modulus of rigidity is defined as:
1
ratio of linear stress to linear strain within elastic limit
2
ratio of shear stress to shear strain within elastic limit
3
ratio of identical stresses acting in thee mutually perpendicular directions on a body to the corresponding volumetric strain
4
ratio of linear stress to lateral strain within elastic limit
