2. (40%) An аluminum (E = 10,000 ksi) shаft A with а diameter оf 3 inches is fastened tо a hоllow steel (E = 30,000 ksi) tube B with an outside diameter of 2 inches and inside diameter of 0.5 inches, which is welded to another steel (E = 30,000 ksi) shaft C with a diameter of 1 inch, as seen in the figure. Both the top and bottom of the assembly are attached to rigid supports. The assembly is loaded as shown in the figure. Ignoring the effect of gravity, determine The normal stresses in shaft A, tube B, and shaft C The deflection of cross section b-b
