I'm not sure in what sense that could be called a single lever...
In this case, the load is the weight being lifted or moved, and the lever is the handle or bar used to exert force on the load. The wheels act as fulcrums by providing a pivot point for the lever to lift the load.
I think they only have one, the pivot point where the two blades are joined. Mechanically, scissors are a first-class double-lever with the pivot acting as the fulcrum.
A fulcrum is the turning point of a lever i.e. The hinge on a door. It is essential to know when learning about the law of the lever i.e. The distance from the fulcrum X force applied on the right hand side = The distance from the fulcrum X force applied on the left hand side. IF the lever is balanced. This can also be written as anticlockwise moments = clockwise moments.
A lever is simply a solid structure on which forces act. The human thumb is therefore made up of a number of classic levers. The joints make up the fulcrums, the tendons attachment points apply the effort, and the force is applied at the end of the thumb.
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.

no they can br found almost anywhere but typicly they are part of the lever
the fulcrum between the effort and load B. effort applied in the same place C. two loads and fulcrums D. the fulcrum at one end of the lever
the fulcrum between the effort and load B. effort applied in the same place C. two loads and fulcrums D. the fulcrum at one end of the lever

Joints
The plural of fulcrum is fulcra or fulcrums.
Scissors are a simple machine. A simple machine makes work easier to do. (not hard work) What type of simple machine are they? They are a lever. Levers have fulcrums or pivot points. The pivot point of the scissors are the crossing section.
Gwen stefani: who who ind it up who who
Yes, it is all three classes of lever depending on the point in the stroke. Your hands are the fulcrums and the oar is the beam.If you use oarlocks then it is a first class lever with the fulcrum in the center.If you use it as a paddle then it is a third class lever with the fulcrum as mentioned before in the hand opposite the load.
Some of the levers in the human body include those seen in the bones and muscles. For example, the bones act as rigid levers, joints serve as fulcrums, and muscles provide the effort. This lever system enables movement and functionality in various parts of the body.
