A rod consisting of two cylindrical portions AB and BC is restrained at both ends. Portion AB is made of steel (E, = 200 GPa, as = 11.7 x 10-6/°C) and portion BC is made of brass (E = 105 GPa, ? = 20.9 × 10-6/°C). IF the load P=750 N applies at "B" find the reaction at "A" and at "C" for the indeterminant shaft. A -25-mm diameter 320 mm -50-mm diameter 450 mm B C
