When the sun gear of a simple planetary gearset is the input member and the ring gear is held stationary,which of the following best describes the output?

Question

Quizplus · Accepted Answer

When the sun gear is the input and the ring gear is held stationary in a simple planetary gearset, the planetary carrier (which typically outputs to the wheels in an automotive application) rotates at a reduced speed compared to the input. This configuration provides maximum forward reduction, as the planetary gears have to rotate around the stationary ring gear, significantly reducing the output speed relative to the input speed.
