The shear modulus of elasticity G is:
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The shear modulus of elasticity/rigidity G is a material's ability to resist deformation, it is defined as the ratio of tangential stress to the shearing strain within the elastic limit. It can be understood better by the following (where y=θ).

About Young's Modulus and Stress-Strain
Stress and strain describe how a solid deforms under an applied force, while Young's modulus is the ratio of tensile stress to tensile strain within the elastic limit. The topic includes elastic and plastic behaviour, Hooke's law, the stress strain graph and the difference between stiffness, strength and breaking stress.
