# Modulus of Rigidity

## Shear Modulus (Modulus of Rigidity) is the elasticity coefficient for shearing or torsion force.

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)"

Modulus of Rigidity can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material.

The definition of Modulus of Rigidity:

- the ratio of shear stress to the displacement per unit sample length (shear strain)
