Young modulus for the perfectly rigid body is
Correct answer: C. infinity
- A. 1
- B. 0
- C. infinity
- D. 40
Explanation
Young's modulus (E) is a measure of a material's stiffness. It is defined as the ratio of stress (σ) to strain (ε):E = σ/εA perfectly rigid body does not deform under any applied stress. This means that the strain is always zero, regardless of the stress. Therefore, the Young's modulus of a perfectly rigid body is infinite.
