3. (40%) A steel shaft (G=10,000 ksi) is loaded as shown in the Figure. The left end (section A) is attached to a rigid wall. The applied torques are at sections labeled B, C, D, and E. The length of each segment is shown in the figure. The diameters are: dAB = dBC =  10 cm, dCD =  8 cm, dDE = 5 cm. Determine: The maximum shearing stress in the shaft. The rotation of a section at the right end with respect to its no-load position.

2. (40%) An aluminum (E = 10,000 ksi) shaft A with a diameter of 3 inches is fastened to a hollow 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
