A highly elastic material is deformed least on loading and retains its original form on removal of the load. Which of the following is the most elastic material ?
Correct answer: A. Steel
- A. Steel
- B. Glass
- C. Rubber
- D. Brass
Explanation
Elasticity here means resistance to deformation under a given load, so the material with the highest modulus of elasticity is considered most elastic. Steel deforms much less than rubber, brass, or glass under the same stress.
