The elastic energy stored per unit volume in terms of longitudinal strain ' ' and Young's modulus ' Y ' is

Options

  1. AY ^2 2
  2. B1 2 Y
  3. C2 Y ^2
  4. D2 Y

Correct answer

A. Y ^2 2

Step-by-step solution

The elastic potential energy per unit volume is u = 1 2 By Hook's law, = Y x = 1 2 Y = Y ^2 2
