Elastic Moduli ComparisonMediumQuestion 6334
Question
Steel is more elastic than rubber because:
- ASteel has larger strain for same stress
- BSteel has larger modulus of elasticity (returns to original shape better)Correct
- CSteel is denser
- DSteel has larger volume
Correct answer
Steel has larger modulus of elasticity (returns to original shape better)
Explanation
Higher E means less strain for same stress — steel is more rigid and elastic in engineering sense.
