I believe you are referring to a Pivot.
The point it pivots round. That is when you use the lever which point on the lever does not move.
The fulcrum is the fixed part of a lever. (the pivot point)
a lever
Lever, the fixed point is the fulcrum.
the length of the fulcrum can be increased in proportion to the length behind the pivot point or leverage point. this will increase the power delivered by the lever. Also the force applied to the end of the fulcrum will also delivers more power from the lever. it is said amongst physic students and thier teachers that if you have a long enough lever and can place against the proper stationary pivot point (heal) you can move anything.

Move the focal point of the leaver.
Well, a lever is a machine consisting of a bar that is free to move around a fixed point, changing the amount of force that must be exerted to move an object. A screwdriver has a handle, and attached to that is a bar, with a sharp tip that fixes onto a screw. It can be considered a lever since you can move the screwdriver around the fixed point, eg, the handle and nail, and can move an object, eg the nail.
A rigis bar that pivots about one point and that is used to move an object at a second point by a orce applied at a third.
A rigid bar that pivots about one point and that is used to move an object at a second point by a force applied at a third.
A rigid bar that pivots about one point that is used to move an object at a second point by a force applied at a 3rd.
A stiff rod that rotates around a pivot point is called a lever. It is a type of simple machine that is used to help move a heavy or firmly fixed load.
Lever, the fixed point is the fulcrum.
The point where a lever pivots is called a fulcrum.
the length of the fulcrum can be increased in proportion to the length behind the pivot point or leverage point. this will increase the power delivered by the lever. Also the force applied to the end of the fulcrum will also delivers more power from the lever. it is said amongst physic students and thier teachers that if you have a long enough lever and can place against the proper stationary pivot point (heal) you can move anything.
