There is a change in length when a 33000 N tensile force is applied on a steel rod of area of cress-section 10-3 m2. The change of temperature required to produce the same elongation, if the steel rod is heated, is (modulus of elasticity of steel = 3 × 1011 N/m2, coefficient of linear expansion of steel = 1.1 × 10-5/°…….
