The modulus of rigidity is the ratio of
A). Longitudinal stress to longitudinal strain
B). Volume stress to volume strain
C). Shearing stress to shearing strain
D). Tensile stress to tensile strain
Shearing stress to shearing strain
The modulus of rigidity, also known as shear modulus, is defined as the ratio of shear stress to shear strain of a structural member. This property depends on the material of the member: the more elastic the member, the higher the modulus of rigidity.
