Question

elastic behaviour on the basis of spring ball model of solid​

Answer 1

Here the balls represent atoms and springs represent inter-atomic forces. If we try to displace any ball from its equilibrium position, the spring system tries to restore the ball back to its original position. Thus elastic behavior of solids can be explained in terms of microscopic nature of the solid.

Answer 2

Answer :

• The atoms and molecules are bonded together by interatomic or intermolecular forces.
• Because of the intermolecular and intramolecular forces they stay in stable equilibrium position.
• When force is applied, the solid deforms, the atoms and molecules diplace from their equilibrium position.
• This way change in interatomic distances takes place.
• After the force is removed, the atoms and molecules come back to their equilibrium position.
• In the spring ball model, spring is said to be the interatomic or intermolecular distance and the balls are the atoms.
• The balls in this model are connected to each other by springs.
• If we displace a ball, the spring tries to restore the position of the ball back.
• Through this model, we can understand the microscopic view of the elastic solids.
