There is some change in length when a 33000 N tensile force is applied on a steel rod of area of cross-section 10^-3m² . The change of
temperature required to produce the same elongation of the steel rod when heated is

$\left(\mathrm{Y}=3\times {10}^{11}\mathrm{N}/{\mathrm{m}}^2,\alpha =1.1\times {10}^{-5{/}^0}\mathrm{C}\right)$
