Which gear train is used for higher velocity ratios in a small space?

A Simple gear train
B Compound gear train
C Reverted gear train
D Epicyclic gear train

Correct Answer: Epicyclic gear train

The epicyclic gear trains are useful for transmitting high velocity ratios with gears of moderate size in a comparatively lesser space. The epicyclic gear trains are used in the back gear of lathe, differential gears of the automobiles, hoists, pulley blocks, wrist watches etc.
