A lever is a simple machine, and it only consists of two material components and two work components. A lever can be made with a beam, or solid rod; a fulcrum, or pivot point; an input force, or effort; and an output for... More »

HowStuffWorks explains that levers work by reducing the force needed to move weights. They achieve this by increasing the distance through which the required force acts. For instance, a 1-kilogram force that acts through... More »

A pivot, also known as a fulcrum, is the point where a load is pivoted. This is a fixed hinge that is connected to the ground. More »

A fulcrum is the fixed support or pivot point for a lever, which is a simple machine used to overcome resistance. The lever is a stiff rod or bar, and the location of the fulcrum determines the class of the lever. Levers... More »

By learning about the six simple machine types, kids can gain a better understanding of how people have always looked for solutions to solve their problems, sought more effective ways to do their work and learned to cont... More »

The first-century inventor and scientist Archimedes is remembered by physicists as the originator of the principles of mechanics, buoyancy, the lever and the pulley, according to Famousscientists.org. Perhaps his best-kn... More »

The six simple machines are the inclined plane, wedge, screw, lever, wheel and axle, and pulley. Each machine is capable of reducing the amount of force needed to complete a task. More »
