# What is modulus of rigidity?

The modulus of rigidity is defined as the ratio of tangential stress to shear strain.

### Modulus of rigidity

Shear Modulus of elasticity is one of the measures of mechanical properties of solids. The shear modulus of material gives us the ratio of shear stress to shear strain in a body.

• Measured using the SI unit pascal or Pa.
• The dimensional formula of Shear modulus is M1L-1T-2.
• It is denoted by G.
