A steel bar is constrained to just fit between two fixed supports when T1 = 74° C. If the temperature is reduced to T2=23° C. determine the tensile force developed in the bar. The bar has a circular cross-section of diameter is 22mm. The coefficient of thermal expansion is 12 x 10-6 /° C and E = 200GPa. Give your result in Newtons as a positive integer.
