Question

What is elasticity of materials?​

Answer 1

$\underline{\underline{\Huge\mathfrak{Answer-: }}}$

★$\bold{Elasticity\: of\: materials-:}$It is the property of the body due to which the body regains its original configuration (length,volume or shape) when the deforming forces are removed. The body which has this property is called elastic body.

Answer 2

$\bf{\huge{\mathfrak{\boxed{\red{Elasticity\:}}}}}$

Elasticity is the ability of a material to return to its original shape and size after being stretched, compressed, twisted or bent.

• Elastic deformation (change of shape or size) lasts only as long as a deforming force is applied to the object, and disappears once the force is removed.
• Greater forces may cause permanent changes of shape or size, called plastic deformation.
