What is the Modulus of Rigidity (Shear Modulus)
Modulus of rigidity, also known as shear modulus, is a measure of the elastic shear stiffness of a material. It is defined as the ratio of shear stress to the shear strain. It can be used to explain why a material resists transverse deformations. A way to measure the mechanical properties of solids is to use the shear modulus of elasticity. The SI unit for the Modulus of rigidity is Pascal (Pa) or N/m². It is denoted by G, S, or μ
In simple terms, the Modulus of rigidity is a measure of how much a material resists deformation when a force is applied perpendicular to its surface.

Modulus of Rigidity Definition
Modulus of Rigidity, also known as shear modulus, is the elastic coefficient for shearing or torsion force. It gives us a measure of how rigid a body is. It is defined as the ratio of shear stress to the shear strain.
Modulus of Rigidity
Modulus of rigidity also known as shear modulus, is used to measure the rigidity of a given body. It is the ratio of shear stress to shear strain and is denoted by G or sometimes by S or μ. The modulus of rigidity of a material is directly proportional to its elastic modulus which depends on the material’s nature and properties.
In this article, we will talk about what Modulus of rigidity is, its formula, examples, and applications.
