energy definition of lever - EAS
- A lever is a beam connected to ground by a hinge, or pivot, called a fulcrum. The ideal lever does not dissipate or store energy, which means there is no friction in the hinge or bending in the beam.

A lever is a type of simple machine, which creates a mechanical advantage to perform tasks by changing the magnitude and/or direction of forces. A lever needs a fulcrum (see figure 1), which is the central pivot for the system to manipulate forces. A lever also needs some sort of rigid bar or rod placed in some position … See more
Levers use the principle of torque(the measure of the force applied on something at a distance from a pivot), in their operation. With levers, the position of the fulcrum determines the dist… See more
There are 3 types (or classes) of levers: 1. Class-1 levershave the fulcrum in the middle, and the applied force is up or down on one of the ends, with the output force being in the opposite direction on the other end. Examples of cla… See more

A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifie…
