A highly elastic material is deformed least on loading and retains its original form on removal of the load. Which of the following is the most elastic material?

Solution (By Examveda Team)

Rubber is the most elastic material among the options provided. A highly elastic material deforms the least on loading and retains its original form on removal of the load. Rubber exhibits high elasticity due to its molecular structure, which allows it to undergo significant deformation under stress and return to its original shape once the stress is removed.

Steel is a strong material but not as elastic as rubber. It exhibits more plastic deformation under stress, meaning it retains some of the deformed shape even after the load is removed.

Glass is brittle and exhibits minimal elasticity. It fractures easily under stress and does not return to its original shape once deformed.

Brass is a metal alloy that is ductile but not as elastic as rubber. It deforms plastically under stress and does not regain its original shape completely upon load removal.

Therefore, Option C: Rubber is the most elastic material among the given options.
