Definitions:

Countershafts Rotate

Output Speed

The rate at which an output shaft rotates, typically measured in RPM (revolutions per minute), indicative of a machine's or component's performance.

Input Speed

The rotational speed at which power or motion enters into a system, such as the speed at which an engine's driveshaft rotates.

Gearset

An assembly of gears designed to transfer mechanical energy from one section of a machine to another.
