The composite shaft, consisting of aluminum, copper, and steel sections, is subjected to the loading shown. The cross-sectional areas of sections AB, BC, and CD are AAB = 0.09 in², ABC = 0.15 in², and Acp = 0.05 in², respectively. The modulus of elasticity for each section are shown in the figure. Neglect the size of the collars at B and C.
