◾️☑️A good spring will be that in which a large restoring force is developed on being deformed. This in turn depends on the elasticity of the material of the spring. Since Young's modulus for steel is more than that of copper, therefore the springs made of steel and not of copper.

Answer 2

Explanation:

◆Spring is made up of stell beacuse of its elasticity.

◆As per Youngs Modulus,Steel is adviced to use,not copper

◆Copper is hard ,it doresnt get elasticity.
