A rod consisting of two cylindrical portions AB and BC is restrained at both ends. Portion AB is made of steel (Es = 200 GPa and αs = 11.7 × 10-6/°C) and portion BC is made of brass (Eb = 105 GPa and αb = 20.9 × 10-6/°C). Knowing that the rod is initially unstressed, determine the compressive force induced in ABC when there is a temperature rise of 70°C. (Round the final answer to one decimal place.)
