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.
