There is some change in length when a 33000N 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, if the steel rod is heated, is (The modulus of elasticity is 3×1011N∕m2 and the coefficient of linear expansion of steel is 1.1×10−5∕‌∘C).
