3.57 At a time when rotation is prevented at the lower end of each shaft, a 50-N-m torque is applied to end A of shaft AB. Knowing that G = 77.2 GPa for both shafts, determine (a) the maximum shear- ing stress in shaft CD, (b) the angle of rotation at A. r = 75 mm 18 mm Fig. P3.57 B aigus 15 mm r = 50 mm D 240 mm
