Question

Why the spring is made up of steel in comparison of copper
A) Copper is more costly than steel B) Copper is more elastic than steel C) Steel is more elastic than copper D) None of the above

Answer 1

Option C is correct.

Answer 2

$\underline{\underline{\Huge\mathfrak{Answer-: }}}$

◆A spring will be better one, if a large restoring force is set up in it on being deformed, which in turn depends upon the elasticity of the material of the spring. Since the Young's modulus of elasticity of steel is more than that of copper, hence steel is preferred in making the springs.
