The Young's modulus for a perfectly rigid body is
Correct answer: B. infinite
- A. zero
- B. infinite
- C. 1
- D. none of these
Explanation
Young's modulus (Y) is a measure of the stiffness of a material. For a perfectly rigid body, which does not deform under any stress, the Young's modulus is considered to be infinite because it experiences no strain regardless of the applied stress
