Question
A rod consisting of two cylindrical portions AB and BC is restrained at both enas. Portion AB is made of steel (E, - 29 × 10° psi, a, - 6.5x 10-9PF) and portion BC is mace of
aluminum (E, - 10.4x 10° psi, a, - 13.3x 10-9PF). Knowing that the rod is initially 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.
