Lever/Lever A lever is a rod that pivots around a point. When you apply a force at the end of the lever it is likely to cause it to turn the fulcrum to the direction of the force. This rotates the fulcrum, increasing the applied force, allowing you to lift or move something that would require more force if you tried to apply it directly to the load. The distance between the fulcrum of the lever and the point at which you apply force determines the most effective movement. This is referred to as the mechanical advantage. The greater the length of the lever, the larger the mechanical benefit. You can calculate the advantage by dividing the distance from the fulcrum to the point where you're applying the force by the distance between the fulcrum and where you will end the lever. Levers can have a variety of effects depending on the way forces are applied. For example the class 2 lever has a tendency to turn in the opposite direction to when the force of effort is applied (like a T-totter). The forces produced when you push on the handle of a front door can result in rotational effects similar to these. However, levers don't create energy. They multiply the force by changing small amounts of effort applied over a longer distance into larger amounts of force that are applied over shorter distances.
