imple machines help us change the amount of force or the direction of the force needed to move an object. Find out how by learning more about levers. Major Funding by the Laura Moore Cunningham ...

The film *Spinning Levers* explores the fundamental mechanics of levers and gears, illustrating their role in various everyday applications and in the complex workings of a car’s transmission.

When you push or pull with a simple machine, you are applying a force and doing work. And, if you get more force out of a machine than you put into it, then that machine has a mechanical advantage.

This video explores different methods that can be use to amplify a force, and focuses on three types of machine - levers, pulleys and gears. The amplification of a force is called mechanical advantage ...
