What is a “fulcrum” and how do I find it?

A fulcrum is a point of support or balance that allows a lever to work. It is the point at which a lever pivots and the force is applied. The fulcrum can be found by looking for the point of balance or the point at which the lever pivots. This can be done by looking at the shape of the lever and determining where the balance point is or by placing the lever on a flat surface and seeing where it pivots. The fulcrum is usually located at the center of the lever, but this can vary depending on the type of lever and the forces applied to it.
