Fig.15.38 shows a compound epicyclic gear train in which two sun gears S, and S, are integral with the input shaft X. The arm B, is integral with the output shaft Y. The planet gear P2 revolves on a pin attached to arm B, and meshes with gear S, and annular gear A. The annular gear A, is coaxial with the input shaft. The planet gear P, meshes with the fixed annular gear A, and sun gear S. The gear P revolves on a pin fixed to gear 42. The number of teeth on gears are: S = 26, S = 31, 4 = 88, 4 = 83. The input power on shaft X is 10 kW at 1000 rpm cccw. Find (a) the speed and torque at shaft Y, assuming efficiency of 96%, and (b) the torque required to hold the gear A, stationary.
