A rod consisting of two cylindrical portions AB and BC is restrained at both enas. Portion AB is made of steel (E, - 29 x 10° psi, a, - 6.5 x 10-9PF) and portion BC is made of aluminum (E, - 10.4 x 10° psi, ag » 13.3 × 10-9F). Knowing that the rod is initialy unstressed, determine (a) the normal stresses induced in portions AB and BC by a temperature rise of 70'F, (b) the corresponding deflection of point B. + 24 in.→ 32 in. → A В C 2--in. diameter 15-in. diameter Answer for (a), GAB = ksi, Gec = ksi (magnitude only pls and use up to 2nd decimal place) Answer for (b), 8s = in (do not use scientific notation, use up to 3 significant figures)
