There is some change in length when a 33000 N tensile force is applied on a steel rod of area of cross-section 10^-3 m^2. The change of temperature required to produce the same elongation, if the steel rod is heated, is (The modulus of elasticity is 3 xx10^11 N m^-2 and the coefficient of linear expansion of steel is 1.1 xx10^-5//^@c)
