Question

The train value of a gear train is:

• A. Equal to velocity ratio of the gear train
• B. Reciprocal of velocity ratio of the gear train
• C. Always greater than unity
• D. Always less than unity

Hint:

Knowing the train value helps in designing gear systems for desired speed reductions or increases.

Answer 1

The Correct Option is A

Understanding gear train terminology.
The train value of a gear train is defined as the ratio of the speed of the first gear to the speed of the last gear, which is essentially the velocity ratio of the gear train.
