2. The rear spring of an automobile has 9 leaves, each with an average thickness of 0.242 in.and a width of 2 in.; material is SAE 9261, OQT 1000°F. The length of the spring is 56 in. andthe total weight on the spring is 1300 lb. Assume the spring to have the form shown in Fig. 6.22(b), Text. Determine (a) the rate of the spring, (b) the maximum stress caused by the deadweight. (c) What approximate repeated maximum force (0 to Fmax) would cause impendingfatigue in 105 cycles, the number of applications of the maximum load expected during theordinary life of a car? (If the leaves are cold rolled to induce a residual compressive stress onthe surfaces, the endurance limit as Su/2 should be conservative.)
