Young's modulus of a perfect rigid body is

Young's modulus of a perfect rigid body is

Options

  1. Azero
  2. Bunity
  3. Cinfinity
  4. DBetween (a) and (b)

Correct answer

C. infinity

Step-by-step solution

For a perfect rigid body, strain is always zero, for all values of stress. As, Young's modulus, Y= Normal stress  I.ongitudinal strain Y=\frac{\text { Normal stress }}{\text { I.ongitudinal strain }} So, its Young's modulus would be infinity.
