2. (40%) Shаft A hаs а mоdulus оf elasticity оf 10,000 ksi and a diameter of 3 inches. It is fastened to a hollow tube B (E = 30,000 ksi) with an outside diameter of 2 inches and inside diameter of 0.5 inches, which is welded to another shaft C (E = 30,000 ksi) 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
