5. The composite beam is made of 6061-T6 aluminum (4) and C83400 red brass (B). Determine the dimension h of the brass strip so that the neutral axis of the beam is located at the seam of the two metals. What maximum moment will this beam support if the allowable bending stress for the aluminum is (allow) al 128MPa and for the brass (allow) br=35MPa? (Eal = 68.9GPa, Er = 101GPa) = = 150 min 50 mm
