Young's ModulusMediumQuestion 6320

Question

Young's modulus of steel is ~2×10¹¹ Pa and rubber is ~10⁶ Pa. This means:
  1. A
    Steel stretches more
  2. B
    Rubber stretches more for same stress
    Correct
  3. C
    Same deformation
  4. D
    Rubber is stiffer

Correct answer

Rubber stretches more for same stress

Explanation

Lower Y → more strain for same stress. Rubber stretches more for the same stress.
