Question

A 2m long wire is stretched by 0.5cm. Calculate the elastic potential energy per unit volume if the Young's modulus of the material of the wire is Y=8×10¹⁰ N/m^-2

Answer 1

The potential energy stored in a stretched wire is given by,

\(U = 2.5\times10^4\,Jm^{-3}U \) will be the potential energy stored in a stretched wire.
