Question

15 In a typical epicyclic gear train, a fixed sun gear (S) having 100 teeth is in mesh with a planet gear (P) having 25 teeth. The planet gear rotates freely on a pin that is attached to an arm (L). If the arm makes 2 rpm about the axis of gear S then the gear P makes a speed of: (3 Points) 8 rpm 10 rpm 6 rpm None of the mentioned 12 rpm 9 rpm

Step 1

The gear ratio is given by the formula: Gear Ratio = Number of Teeth on Sun Gear / Number of Teeth on Planet Gear In this case, the sun gear (S) has 100 teeth and the planet gear (P) has 25 teeth. Therefore, the gear ratio is: Gear Ratio = 100 / 25 = 4 This Show more…
