Question

The modulus of elasticity of steel is greater than that of rubber because under the same stress

• A. the strain in steel is less than rubber
• B. the strain in steel is more than rubber
• C. elongation in steel is more than in rubber
• D. none of the above

Answer 1

The correct option is A

the strain in steel is less than rubber

Modulus of elasticity is inversely proportional to strain for a given stress. If steel and rubber are under the same stress, the strain in steel is less than rubber . Hence steel is more elastic than rubber.
