In the planetary gear train shown in Figure Q2, the annulus A rotates at 300 rpm about the axis of fixed wheel S which has 80 teeth. The armed spider (arm) is driven at 180 rpm. The annulus is connected to input shaft whereas the arm is connected to the output shaft. If the efficiency of gear system is 98% and input torque is 100 Nm, identify the following information regarding these problems (i) The number of teeth on planet gear, P (ii) Holding torque for fixed wheel (iii) Power transmitted by the gear train.

A train travels between stations 1 and 2, as shown in the figure. The engineer of the train is instructed to start from rest at station 1 and accelerate uniformly between points A and B, then coast with a uniform velocity between points B and C, and finally decelerate uniformly between points C and D until the train stops at station 2. The distances AB, BC, and CD are all equal, and it takes 5.63 min to travel between the...
