on the position of the fulcrum
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
first class The point about which a lever rotates is called the fulcrum
Levers. Mostly levers.
Well, there are three classes of levers. Class one levers are seesaws, where the effort force is on one end, fulcrum in the middle and object on the other end moving the opposite direction of the effort force. Class two levers are wheelbarrows, where the effort force is on one end, the fulcrum on the other and the object in the middle. Class three levers are like baseball bats, the fulcrum is on one end, the effort force in the middle and the object on the end. Other examples include: a golf club, catapult, an arm, a door, a tennis racket, a fly swatter or a stick.
levers are classified by the locations of the input and output forces relatively to the fulcrum

There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.

first class The point about which a lever rotates is called the fulcrum
There are multiple classes of levers, which can be used for varying situations. For example, some can be used for lifting tools, whereas others can be used for pulling large amounts of weight. Often, it is not otherwise possible to move large amounts of weight without these varying uses of levers, which speaks to their usefulness.
seesaws are and example of levers,as one person goes up the other goes down in a simple lever position.
All the levers in the world can be grouped in 3 classes, depending on how the effort point, the load point, and the fulcrum are lined up. Class I . . . fulcrum (pivot) is in the middle. Class II . . . load is in the middle. Class III . . . effort is in the middle. Each individual lever can only belong to one class.
i forgot but if you get mad please firgive me but dusews
The fulcrum can only ever be called the fulcrum. You may be asking about the three classes of levers: if so, you need to ask the question with enough description to allow an answer.
Levers can make exercise more difficult depending on how they are used. They can help to make the resistance stronger so a muscle has to work harder.
lenght of the effort arm divided by lenght of the load arm
