Solution

The correct option is B 2 1 4 3
  • Young's modulus is ratio between stress and strain within elastic limit. It can be expressed as: E = Stress/strain
  • Poisson's ratio is defined as the negative of the ratio of the lateral strain to the longitudinal strain within elastic limit
  • Bulk modulus: The ratio of the change in pressure to the fractional volume compression.
  • Modulus of rigidity or shear modulus is the rate of change of unit shear stress with respect to unit shear strain for the condition of pure shear within elastic limit
