An aluminum [E = 7590 ksi] bar is bonded to a steel [E = 25450 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +468 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.635 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.2124 in.“, find the magnitude of the maximum bending stress in the steel. Steel 0.50 in. 0.50 in. Aluminum 1.50 in.
