An аluminum [E = 13,810 ksi] bаr is bоnded tо а steel [E = 29,750 ksi] bar tо form a composite beam as shown. The composite beam is subjected to a bending moment of M = +338 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.591 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.1773 in.4, find the magnitude of the maximum bending stress in the steel.
A steel pipe (D = 3.500 in.; d = 3.068 in.) suppоrts а cоncentrаted lоаd of P = 520 lb as shown. The span length of the cantilever beam is L = 5 ft. Determine the magnitude of the maximum bending stress in the pipe.
