As shown in the figure a planetary gear train consist of the arm C coupled to two gears A
and B with 40 and 60 teeth respectively. If the arm rotates at 150 rpm in the anticlockwise
direction about the center of the fixed gear A. Calculate the speed of gear B. How fast will
gear B move if the gear A makes 300 rpm in the clockwise direction instead of being fixed.

- The figure below shows a two-stage helical gear set. Pinion 2, which is in the converter position, transfers a certain rotation moment from the shaft to gear 3 in the first stage by rotating in the direction of the clock in the front view (or in the Z direction) shown in the figure. on shaft B, the pinion gear No. 4 is positioned with gear No. 3, which receives and/or transmits the drive from different gears. The number 4 Pinion in the second stage drives the number 5 gear, converting the input moment in the system to the output moment and providing movement transfer.
