PROBLEM 3.29 While the exact distribution of the shearing stresses in a hollow-cylindrical shaft is as shown in Fig. a, an approximate value can be obtained for ?max by assuming that the stresses are uniformly distributed over the area A of the cross section, as shown in Fig. b, and then further assuming that all of the elementary shearing forces act at a distance from O equal to the mean radius of the cross section. This approximate value where T is the applied torque. Determine the ratio of the true value of the maximum shearing stress and its approximate value for values of respectively, equal to 1.00, 0.95, 0.75, 0.50, and 0.
