A rod consisting of two cylindrical portions AB and BC is restrained at both ends. Portion BC is made of steel (Es = 29 × 106 psi and αs = 6.5 × 10-6/°F) and portion AB is made of aluminum (Ea = 10.4 × 106 psi and αa = 13.3 × 10-6/°F). The rod is initially unstressed before a temperature rise of 74°F. Determine the normal stress induced in portions AB and BC due to the temperature rise. The normal stress induced in portion AB is ___ ksi. The normal stress induced in portion BC is___ ksi.
