Question
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 = 0.10in2 , ABC = 0.15in2 , and ACD = 0.05in2 , respectively. The modulus of elasticity for each section are shown in the figure.
Determine the normal stress in section AB.
Determine the normal stress in section BC.
Determine the normal stress in section CD.
Determine the displacement of end A with respect to end D.

Determine the normal stress in section AB. Determine the normal stress in section BC. Determine the normal stress in section CD. Determine the displacement of end A with respect to end D.Explanation / Answer
AB= P AB/ A AB =2/0.09=22.2 ksi
BC= P BC/ A BC =5/0.12=41.7 ksi
CD= P BC/ A BC =1.5/0.06=25 ksi
ND=PL/AE= 2(18)/ (0.09)(10)(10^3) +(-5) (12)/ (0.12)(18)(10^3)+(-5)(16)/ (0.06)(29)(10^3)= -0.00157 IN
