Name the law relating stress and strain.

Stress - Strain graph of two materials is shown below: State the law which relates stress with strain.

A light ray is travelling from rarer to denser medium. State the law relating i and r for retracted ray

Prove that the elastic potential energy density of a stretched wire is half the product of stress and strain.

When an external force deforms a solid, internal restoring forces are developed in the body giving rise to stress and strain. Define stress and strain.

When an external force deforms a solid, internal restoring forces are developed in the body giving rise to stress and strain. Draw the stress-strain diagram and mark the positions of elastic limit and the regions of elastic and plastic behaviors.

Name the law which explains the relation between current and the magnetic field produced by the current.
