Which of the following is more elastic?
Correct Answer: B — Steel
Explanation:
Concept: Elasticity is the property of a material to regain its original shape after deformation when the external forces are removed. All materials are plastic to some extent but the degree varies, for example, both mild steel and rubber are elastic materials but steel is more elastic than rubber. Modulus of Elasticity or Young’s modulus is the slope of the stress-strain curve in the elastic region.
