True (A)
Elasticity is the ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed.
Elasticity is the ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed.
Elastic Limit is the limit beyond which the material will no longer return to its original shape when the load is removed.

Study Notes
Material Properties
-
Toughness: Represents a material's capacity to absorb significant energy prior to fracturing; crucial for applications that endure impacts.
-
Stiffness: Defined as the ratio of applied steady force to the resultant displacement in an elastic material; indicates how resistant a material is to deformation.
-
Resilience: Reflects the ability of a material to absorb energy upon deformation and release it without any permanent changes; essential for materials that undergo cyclic loading.
-
Elasticity: Describes the capability of a material to revert to its initial shape and dimensions after the removal of deforming forces; a vital property for many structural materials.
-
Elastic Limit: Marks the maximum stress a material can withstand while still being able to return to its original form; exceeding this threshold results in permanent deformation.
