Levers can be all of them. A first class lever is when the pivot (funcrum) is in the middle. A second class lever has the load (resistance) in the middle, and the third class lever has the effort (force) in the middle. For example, a see-saw is a first class lever because the fulcrum is the in middle. A exmaple for a second class lever would be a can opener because the load, the can, is in the middle. And last, the thrid class lever is a arm because the effort is in the middle, because your elbow gives the effort to move the arm.
Levers can be classified as first, second, or third class based on the relative positions of the fulcrum, effort, and load. First-class levers have the fulcrum positioned between the effort and load, second-class levers have the load positioned between the fulcrum and the effort, and third-class levers have the effort positioned between the fulcrum and the load.
They are the 3 types of lever a first class is where the fulcrum is in the middle a second class lever is were the load is in the middle and on a 3rd class lever the effort is in the middle. Or at least I think. The effort is well the person putting the effort. The load is the thing your carrying. I really don't know how to describe the fulcrum though.
A lever is a rigid bar that is free to rotate, or pivot, on a fixed point. The fixed point on a lever is a fulcrum.
Frist-Class Levers
Secound-Class Levers
Third-Class Levers
The distinction among the classes of levers is determined by
the physical sequence of the fulcrum, effort, and load.
When they're arranged in exactly that sequence, you've got yourself
a 3rd Class lever.

What class of lever is a hole punch?
If you have the fulcrum ( unmoveable pivot point) between your hand and the object you are prying, it is a 1st class. If the end of the pry bar is wedged into a fulcrum and you are trying to move something between the end of the bar and your hand, it is a 2nd class. My class used a pry bar as " a classic example of a 1st class lever"....sometimes true, but very common to use it as a 2nd class as well ( e.g. moving an alternator, etc...)
What is some uncommon 3rd class levers?
Some uncommon examples of third-class levers include tweezers, ice tongs, and some fishing rods. Third-class levers have the effort between the fulcrum and the load, increasing the speed and distance traveled by the load.
What is some information about levers?
Levers are simple machines that consist of a rigid bar (lever arm) that pivots on a fulcrum to help lift or move objects. There are three types of levers based on the relative positions of the effort, fulcrum, and load: first-class lever, second-class lever, and third-class lever. Levers are commonly used in everyday items like seesaws, crowbars, and scissors.
Why are fishing rods third class levers?
Fishing rods are considered third-class levers because the effort (force applied by the angler) is between the fulcrum (where the rod is held) and the load (the fish at the end of the line). This arrangement allows for greater speed and distance to be achieved when casting the line.
What is first class levers?
== == There are 3 class levers, 1st, 2nd and 3rd. A 1st class lever is a lever with its Fulcrum in between the Effort and the Load. An example is the scissors and a roller coasters and glow sticks.....!!!!! (JUST REMEMBER FLE 123 1= fulcrum in the middle 2=Load in the middle 3=Effort)A Class-I lever is a lever set up like a see-saw ... with the effort andthe load located at opposite ends, and the pivot between them.Class-II and Class-III levers both have the pivot at one end.Class-II . . . the effort is at the other end, and the load is in the middle.Class-III . . . the load is at the other end, and the effort is in the middle.A see saws is the easiest description of a 1st class lever. The fulcrum is in the middle and the force is applied on one side. Scissors and pliers are other 1st class levers.Examples of first class levers are-see saw-trebuchet-scissors-spud bar-chop sticksa form of lever in which the input and output forces are on either side of the fulcrumscissors ,beam balance , seesaw,oars
