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.

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 ...

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 ...

Throughout history, humans have developed several simple machines to make work easier. The most notable of these are known as the "six simple machines": the wheel and axle, the lever, the inclined ...

Tuesday’s Google Doodle celebrates the 131st anniversary of the day Friedrich Soennecken filed a patent for what would soon become arguably the sleekest, most elegant example of applied physics known ...
