Lever/Lever A lever is a rod that pivots around a point. When you apply force to the end of the bar, the fulcrum is likely to rotate in the direction that the force is applied. This motion increases the force and lets you lift or move objects that normally require more force to lift. The distance between the fulcrum and the place where you apply the force determines how far the lever can move. window handles www.repairmywindowsanddoors.co.uk is called the mechanical advantage. The advantage in mechanical terms increases as the lever is extended. You can calculate the advantage of mechanical by dividing the distance from fulcrum point to the point at which you are applying force by distance between the fulcrum point and end of the lever. Levers can have different effects based on how forces are applied. For example, a class 2 lever is inclined to turn in the opposite direction when the force of effort is applied (like a T-totter). If you press on the door's handle, the forces will produce similar rotational effects to this. However, levers don't create energy. Levers increase the force by changing small amounts of effort applied over a longer distance into greater amounts of force that are applied over shorter distances. Levers are used to lift heavy objects and transport huge amounts of cargo.
