What is Elasticity ?

Elasticity is a material's ability to recover to its original shape following deformation. It is measured by the elastic modulus, which determines the material's stiffness. Hooke's Law describes the linear relationship between stress and strain in an elastic material. There is an elastic limit beyond which permanent deformation occurs. Understanding elasticity helps in material selection, structural design, and predicting material behavior under stress.
