Elastic Behavior of Solids

-In solids, atoms and molecules are arranged in such a way that such  molecules is acted upon by the forces due to the neighboring molecules.

- These forces are known as intermolecular forces.
- When no force is applied each molecules are in equilibrium.

- When it is slightly pulled its length increases. In other word, the solid is deformed.
- This force is deforming force and when it is removed the body gains original shape and size.
- The force responsible to bring the spring to its original state is reforming force.

Elastic Limit

- Elastic limit is the upper limit of deforming force up to which if deforming force is removed, the body regains its original form completely and beyond which if deforming force is increased, the body loses property of elasticity and gets permanently deformed.
