Fulcrum is part of a lever.
A Fulcrum is a simple machine invented by the greek mathematician Archimedes who theorized that with a large enough fulcrum one could move the Earth. As for use in a sentance? Here ya go. Archimedes used a fulcrum to lift the earth.
means to support on which a lever pivots
I do not know where a man finds the fulcrum that enables him to hold out against such a life.
move the plank closer to the fulcrum to be able to lift the rock off the ground
The senator's strong solutions to the budget deficit became the fulcrum for his election to office.
Levers are classified by where the fulcrum is located.
No, a pulley does not use a fulcrum. A pulley is a simple machine that utilizes a wheel and axle to redirect the force applied to it. It works by changing the direction of the force, not by pivoting around a fulcrum like a lever.
A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use.

yes
A fulcrum is typically easier to use when it is closer to the object being lifted because it requires less force to balance the load. When the fulcrum is farther away, more force is needed to achieve the same lifting effect.
A fulcrum.
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
