A load of 31.4 kg is suspended from a wire of radius `10^(-3)` m and density `9xx10^3 kg//m^3` Calculate the change is temperature of the wire if 75% of the work done is converted into heat. The Young's modulus and the specific heat capactiy of the meterial of the wire are `9.8 xx 10^(10) N//m^2 and 490 J//kg//K` respectively.
