Question

On stretching a wire the elastic energy stored per unit volume is

Answer 1

Answer:

The work done by external applied force during stretching is stored as potential energy (U) in the wire and is called as strain energy in the wire. This is an expression for strain energy or potential energy per unit volume of stretched wire. ... unit is J m-3 and its dimensions are [L-1M1T -2].

Answer 2

Energy density bolte hai

$\frac{energy}{volume}$

energy density = (1/2)*stress*strain.........
