Question

1.A metallic wire is stretched by suspending weight from it. If α is longitudinal strain and Y is the youngs modulus ,show that elastic potential energy per unit volume is given by ½ y α 2 .​

Answer 1

Answer:

here is your answer

Explanation:

A metallic wire is stretched by suspending a weight to it. If α
