Explanation
elasticity is the tendency of a body to oppose the change in its shape and size ( basically its configuration).
- Steel, because a body is said to be more elastic depending on how fast it gains its original shape after removal of external (deforming) force.
- When a force is applied to steel it is deformed but it immediately regains its original shape within a fraction of seconds which is not in the case of rub
- For steel, we require a lot of force to deform a steel wire for a small change in length.
- In case of rubber, a small amount of force can produce a lot of deformation. Such materials, in which a small force can cause a large deformation, are called elastomers. Rubber is an elastomer.
hence , steel is more elastic than rubber .
