Question

1. Given the gear train below, determine the output speed of the planet carrier (arm/ink 7) if the input gear (2) has a speed of 3200 RPM. The ring gear (1) is fixed. N -82, N2 20, N -75, N38, Ns 22. Gear 2 is on a fixed axle (not shown) as are gears 3 and 4 which rotate together. Gear 5 is a normal planet. Note: this is a planetary train attached to a simple train. 4 Start with the simple gear train (gears 2 and 3). R23--N- 3.75+ at. Since ω2 -853.33RPM which is also ws since they're on the same shaft. 3200RPM up For the planetary train: Gearwgearwarmugear rel arm warm N1/NS - warm FNCA NS/N | N1/N4+warm warm we're given ai and ws is found from the first part Filling out the other columns eventually gives us t equation in the bottom, ro :-853.3:1-aar n (1 + N ) r a intį 2709RPM

In the table, how are we calculating the wgear rel arm? this the only column I do not understand
