Derive a formula to calculate the velocity ratio of gears.

Derive a formula to calculate the velocity ratio of gears.

---

A gear is a wheel with equally spaced teeth or cogs around it. The wheel on which the effort is applied is called the driving (input) gear while the load gear is referred to as the driven (output) gear. Suppose the driving gear has n teeth and the driven gear N teeth, then when the driving gear makes one complete revolution the driven gear makes n/N revolutions.

Hence, velocity ratio of a gear system is the ratio of the number of teeth of the driven gear to the number of teeth of the driving gear;
