Question

A wire of length l0l0 is supplied heat to raise its temperature by t. If is the coefficient of volume expansion of the wire and y is the youngs modulus of the wire then the energy density stored in the wire is

Answer 1

Answer:

A wire of length L0 is supplied heat to raise its temperature by T. if γ is the coefficient of volume expansion of the wire and Y is Young's modulus of the wire then the energy density stored in the wire is. Solution : Due to heating the length of the wire increases.
