Use Gear ratio to calculate output torque, speed and rotations based on input values for both Sprockets and Chains as well as Pulleys and Belts. Learn how an idler pulley or sprocket can be used to maintain tension in a belt or pulley. Also learn a trick for determining the direction of rotation of shafts when connected via a belt or pulley.
The application of sprockets and chains most commonly come up on motorcycle drive trains as well as mountain bike drive trains. Belts and pulleys can commonly be found driving alternators and steering pumps in cars as well as timing belts to control the motion of overhead cams for engine intake and exhaust valves.
The study of sprockets and chains in both physics and engineering is based largely on the application of simple gears these systems.
