Pulleys use mechanical advantage, similar to levers, to lift loads ... and the velocity ratio has been calculated as 3. Smaller gears with fewer teeth turn faster than larger gears with more ...

Explains how simple machines, such as levers, pulleys, wheels and axles, and inclined planes, work together to make tasks easier by trading force for distance or vice versa. It illustrates the concept ...

The process in this example is the chain revolving, which in turn moves the gears. This converts one ... is greater than the input motion.Pulleys and levers are good examples of this.
