A load of 31.4 kg is suspended from a wire of radius 10^-3 m and density 9 times 10^3 kg//m^3. Calculate the change in temperature of the wire if 75% of the work done is converted into heat. The Young's modulus and the specific heat capacity of the material of the wire are 9.8 times 10^10 N//m^2 and 490 J.kg^-1.K^-1 respectively.
