Lever/Lever
A lever is a rigid bar pivoted around a point (known as a the fulcrum). When you apply force towards the end, the fulcrum will tend to rotate in the direction that the force is applied. This rotates the force and allows you to lift or move things that would otherwise require more force to lift.
The distance between the fulcrum and the point where you apply the force determines the distance the lever is able to move. This is known as the mechanical advantage. The more the lever extends, the larger the mechanical benefit. You can calculate the advantage of mechanical by dividing the distance from fulcrum point to the point at which you apply force by the distance between fulcrum point and the end of lever.
Levers can have a variety of effects depending on the way forces are applied. For example a lever of class 2 has a tendency to turn in the opposite direction to when the force of effort is applied (like a T-totter).
