Question

Steel is more elastic than rubber because it

(a) requires larger deforming force

(b) is never deformed

(c) is deformed very easily

(d) is harder than rubber

Answer 1

Correct option is (a) requires larger deforming force

Strain produced in rubber is much larger compared to that in steel. This means steel requires larger deforming force, hence it has larger value of modulus of elasticity. Therefore, steel is more elastic than rubber.
