Lever/Lever A lever is a solid bar pivoted around a point (known as a the fulcrum). When you apply a force to the end of the lever it will tend to rotate the fulcrum to the direction of the applied force. This motion increases the force and allows you to lift or move objects that would otherwise require more force to lift. The distance between the fulcrum to the point where you apply the force determines the distance the lever can be moved. This is known as the mechanical advantage. The mechanical advantage increases as the lever gets extended. You can calculate the mechanical advantage by dividing the distance from the fulcrum to the point at which you are applying the force by the distance between the fulcrum and the end of the lever. Levers also have various effects depending on how the forces are applied. A class 2 lever, for example is prone to turning in the opposite direction when an effort force is applied. If you push the door's handle the force will create similar rotational effects to this. However, https://www.repairmywindowsanddoors.co.uk/bow-windowrepair/ don't create energy.
