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.

Discusses the principles of levers, a type of simple machine that helps lift heavy loads by changing the direction or magnitude of force applied. It explains how the position of the fulcrum affects ...

A lever is a simple mechanism that uses a bar to pivot around a fixed point called a fulcrum. Levers can be joined together to form linkages. Simple linkages can be used to change the direction of ...
