______ is the ability of a material to return to its original shape after being deformed.

______ is the ability of a material to return to its original shape after being deformed.

• A. Ductility
• B. Elasticity
• C. Plasticity
• D. Resiliency

Answer: (D)

Elasticity is the property that describes how a material returns to its original shape after the load is removed, as long as the deformation stays within the elastic limit. When stress is applied, the material may deform, but if you stay within this limit, removing the stress lets it snap back to its original dimensions. Ductility is about being drawn into wires or stretched a lot before breaking, which is a different, plastic behavior. Plasticity means permanent deformation that does not fully recover after removing the load. Resiliency is related to the ability to absorb energy and recover, but the specific term for shape recovery after deformation is elasticity.
