In the following figure, axis Y-Y is fixed while axes X-X and Z-Z move with the arm. Gear 7 is fixed to the carrier. Gears 3 and 4, 5 and 6, and 8 and 9 are fixed together, respectively. Gears 3 and 4 move with planetary motion. If the tooth numbers are N1 = 6T, N2 = 20T, N3 = 22T, N4 = 14T, N5 = 36T, N6 = 20T, N7 = 41T, and N8 = 97T, and the input speed is 1200 rpm, determine the speed and direction of the output shaft.
