Next to the wedge, the lever is the simplest tool used by mankind. In its basic form, a single lever is stiff straight rod that rests on a pivot point called a fulcrum.
The length of the rod is L, its length from one end of the rod to the pivot point is l; so the length from the pivot point to the opposite end is L - l.
We can show that F = f (l/(L - l)) increases the input force f to F > f when (l/(L - l)) > 1.0. The ratio (l/(L - l)) is called the mechanical advantage of the lever. EX: If L = 10 and l = 9, then 9/(10 - 9) = 9 is the mechanical advantage. So that F = 9f would be the result.
A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.

A common lever is used to move an object
The arm lever is a force multiplier. In a lever system, the input force is applied over a longer distance than the output force, resulting in an increase in the output force at the expense of a decreased distance. This allows for the amplification of force to overcome resistance or lift heavy loads with less effort.
ANSUL Systems operate automatically when fire linkages are connected and the tension lever is ON. ANSUL can also be deployed manually by pulling the handle.
The pivot point of a lever system is called the fulcrum.

The handles of a wheelbarrow would be the lever of the machine system. The wheel would be the fulcrum or center point. The part of the wheelbarrow that is used as a lever system is the operator. The operator lifts the handles and creates a lever.
A paired lever is a system in which two levers are connected together. The movement of one lever affects the movement of the other lever. This type of lever system is commonly used in mechanical devices to amplify force or speed.

The term used to describe the pivot point of a lever system is the "fulcrum." It is the point on which the lever rotates or pivots when force is applied.

Because to actuate the brake you pull at the brake lever.
There are typically three levers in a city drain system: the flush lever, the control lever, and the drain lever. These levers are used to manage the flow of water and maintain the city's drainage system.
The fulcrum is the lever that is positioned between the force and the resistance in a lever system. It acts as the pivot point around which the lever rotates to apply force to overcome resistance.
