Question

Elastic limit is the point

• A. up to which stress is proportional to strain
• B. at which elongation takes place without application of additional load
• C. up to which if the load is removed, original volume and shape are regained
• D. at which the toughness is maximum

Answer 1

The correct option is C up to which if the load is removed, original volume and shape are regained

Elastic limit is the maximum extent to which a solid may be stretched without permanent deformation of size or shape and returns to original volume and shape when load is removed.
