A wire of length L and cross section A is made of material of young's modulus y. It is stretched by an amount x. What is the work done ?

Two wires A and B, having identical geometricla construction, are stretched from their natural length by smal but equal amount. The young modulus of the wire are Y_A and Y_B whereas the densities are rho_A and rho_B . It is given that Y_AgtY_B and rho_Agtrho_B A transverse signal started at one end takes a time t_1 to reach the other ennd for A and t_2 for B.
