fulcrum
Definition
A fulcrum is the point on which a lever pivots. It is the point where the force is applied to the lever.
The fulcrum is important because it determines how much force is needed to lift a load. The closer the fulcrum is to the load, the more force is needed to lift it. The farther the fulcrum is from the load, the less force is needed to lift it.
For example, if you are trying to lift a heavy rock, you will need to use more force if the fulcrum is close to the rock. However, if you move the fulcrum farther away from the rock, you will need to use less force to lift it.
How can the word be used?
