Elastic Behaviour Of Solids

The atoms in a solid are held together by interatomic or intermolecular forces. These forces keep solid in a stable equilibrium position. When a solid is deformed, the atoms or molecules are displaced from their equilibrium positions. Thus, deformation causes change in interatomic or intermolecular distances. On removing deforming forces, the inter atomic forces tend […]

Elastic and Plastic Body

Elastic Body A body that returns to its original shape and size on the removal of the deforming force (when deform within elastic limit) is called an elastic body. Example: Quartz fibre, Ivory ball and phospher bronze etc. Elasticity The property of matter by virtue of which it regains its original shape and size, when
