A planetary spur gear train as shown in the figure below consists of 34-tooth sun gear in mesh with a planet gear of 22 teeth. The sun gear pitch diameter is 136 mm. During power transmission the arm rotates at1200 rpm while the ring is held stationary, 1- Find the diameters of the planet and ring gears (2 pts) 2- The number of teeth of the ring (2) 3- Determine the rotational speeds of the sun gear (4 pts) 4- Find pitch line velocity of the planet gear (2 pts) planet ring gear ring gear sun gear planet arm am sun gear armi input output bearing
