Question

Relationship between elastic shear stress and shear strain is a) Young's modulus b) Poissons ratio c) Saint-Venant's principle d) Modulus of rigidity e) None of these

Answer 1

Option D is the correct answer.

Step-by-step explanation:

Young's modulus is the ratio of tensile stress and tensile strain.

Bulk modulus is the ratio of pressure and volume strain.

Rigidity modulus is the ratio of shear stress and shear strain.

Here we are asked about relationship between elastic shear stress and shear strain. We have rigidity modulus is the ratio of shear stress and shear strain.

Option D is the correct answer.
