Modulus of Rigidity-FAQs
1. What is Shear Modulus?
Shear Modulus also called Modulus of Rigidity measures a material’s resistance to deformation under shear stress.
2. What is Difference between Modulus of Rigidity and Modulus of Elasticity?
Modulus of rigidity focuses on shear deformation, while modulus of elasticity deals with linear deformation or stretching.
3. What is Bulk Modulus and Rigidity Modulus?
Bulk modulus measures a material’s resistance to volume change, while rigidity modulus (shear modulus) assesses resistance to shear deformation.
4. What is Modulus of Rigidity Formula?
Modulus of rigidity formula is, G = τ / γ
5. What is Unit of Modulus of Rigidity?
Modulus of rigidity unit is pascals (Pa) or gigapascals (GPa).
6. What is the Modulus of Rigidity of Ideal Liquid?
The modulus of rigidity for an ideal liquid is zero. Liquids don’t resist shear deformation like solids, so they have no shear modulus.
7. Modulus of Rigidity is defined as the Ratio of?
Modulus of rigidity is defined as the ratio of shear stress to the corresponding shear strain in a material. It measures how a material deforms under shear forces.
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.
