P5-3

The plenetary gear train has a sun of 40 Teeth, planets of 20 Teeth and a ring of 80 Teeth. The center-to-center distance of the sun to either planet is 0.5in. The angular velocity of the sun is Delta.deltadeltadelata rad/s CCW and the ring 1.2rad/s CW. Determine the angular velocity of the arm and the planet gears.
