Question

A stepped circular bar made of steel is placed between two rigid walls in close fit condition at a temperature of 20°C, as shown in Fig. 2. Determine the stresses in the portions AB and BC when the temperature increases to 90°C. Consider dAB = 1.5xd, dBC = d, d = 20 mm, Est = 200 GPa, and α = 12x10^-6 m/m°C.
