Assertion: Ratio of stress and strain is always constant for a substance. Reason : This ratio is called modulus of elasticity .

Elastic Potential Energy Stored In A Rod

what is meant by elastic potential energy? Deerive an expression for the elastic potential energy of streched wire. Prove that its elasic energy density is equal to 1/2 x stress x strain
