Consider the following statements about elastic constants: (i) Young's modulus relates tensile stress to tensile strain. (ii) Bulk modulus relates stress and volumetric strain. (iii) Shear modulus relates tangential stress and shear strain. (iv) Poisson's ratio is the ratio of longitudinal strain to lateral strain. Which statements are correct?

Options

  1. A(i), (ii), (iii) only
  2. B(ii), (iii), (iv) only
  3. C(i), (ii), (iii), (iv)
  4. D(i), (iii), (iv) only

Correct answer

C. (i), (ii), (iii), (iv)

Step-by-step solution

All definitions are correct, but note Poisson's ratio is lateral strain / longitudinal strain, not reverse (so some examiners trick here).
