Using a lever to lift a stone provides mechanical advantage, allowing you to lift heavier loads with less effort. It also allows for precise control over the lifting process. Lastly, a lever can be easily adjusted or used in various positions to suit different lifting needs.
If you are pulling a nail out of wood, you are using a lever as a simple machine. By applying force to one end of the lever (the nail), you are able to lift the nail out of the wood using the principle of torque.
Probably you are using the board as a lever.
A fixed point at which a lever pivots is called a fulcrum. The location of the fulcrum determines how the lever will move and can affect the amount of mechanical advantage gained when using the lever.
A compound machine consisting of a lever and wedge would typically involve using the lever to apply force on the wedge. For example, using a lever to push down on a wedge to split wood. The lever amplifies the force applied to the wedge, making it easier to perform tasks that would be difficult with just the wedge alone.

Push the lever and the door will open.
It depends on which side of the hammer you're using. If you're using the claw part its a class-1 lever, but if you're using the hammer itself, it's a class-3 lever.
