Study Notes

Gear and Pulley Systems

RPM stands for Revolutions per Minute, a unit of measurement for the rotational speed of a shaft or other rotating component.
Turing force, also known as rotational force, is referred to as Torque.
The gear that is being turned by a motor or other power source is called the Driven Gear.
