The composite shaft , consisting of aluminium, copper and steel sections, is subjected to the loading shown. The cross-sectional areas of sections AB, BC and CD are AAB=0.08 in2, ABC=0.11 in2, and ACD=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. Determine the normal stress in section AB,BC and CD. Also determine the displacment of end A with respect to end D.
