An aluminum [E = 13,570 ksi] bar is bonded to a steel [E = 27,950 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +318 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.587 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.1740 in.4, find the magnitude of the maximum bending stress in the steel.
