Learn how to calculate the gear ratio for a simple set of spur gears. Gears share tangential quantities, which allows them to effectively convert torque into rotation while conserving energy. There is a line of action between gears where the gear teeth mesh. Along the line of action the gears have the same tangential velocity and the action and reaction force between the gear teeth is the same. • The derivation of gear ratio and mechanical advantage ignores frictional losses but covers material commonly found in introductory physics, engineering and courses such as Project Lead the Way Principles of Engineering.
