2. A core made of stainless steel (material 1, E, = 28 Msi) is fully bonded to an inner shell of brass (material 2, E, = 15 Msi), which is fully bonded to an outer shell of aluminum (material 3, Ea = 10 Msi). The rod is subjected to a compressive load, P = 50 kips. Determine: a) the normal stress in the brass and b) the deflection of the composite rod. Dimensions: L= 10 in, di = 1 in, d2 = 2 in, d3 = 3 in. Recall that Msi =10° psi. Ans: ob = 7.76 ksi (C), 8 = 5.176 × 10-³ in (shorter)
