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 ...

Posted: July 16, 2025 | Last updated: July 16, 2025 In this video, we uncover the fascinating world of mechanical advantage through three simple yet powerful machines , levers, pulleys, and gears.

Third class levers (Class 3) place the effort between the fulcrum and the load. If the effort and the fulcrum are further apart, it becomes easier to lift. A third order lever does not have the ...

Example A solid beam 0.5 m long is laid across a pivot to form a simple lever. The pivot is 0.1 m from the end of the beam. Calculate the heaviest load that could be lifted using a force of 500 N.

A lever is a simple machine that can help people do just this. It can also help make other kinds of physical work easier by giving the user a mechanical advantage.

“Nuts & Bolts” riffs on the classic list of simple machines you might recall from grade school. These six devices—the lever, pulley, inclined plane, wedge, screw and wheel—revolutionized ...
