resistance
A lever moves a load by applying a force over a distance. The load can be a heavy object, a piece of machinery, or another lever. The position of the load in relation to the pivot point of the lever determines the mechanical advantage and how easily the load can be moved.
A third class lever has the effort in the middle, with the resistance located at one end, and the fulcrum located at the opposite end. This type of lever is designed to increase the distance the load moves while decreasing the force required to move it.
What is the function of each part of the lever
The fulcrum is the part that the bar sits on to form a lever. The output arm is the part that the load sits on.
Arm is the example of 2nd class lever.

Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
Moving the fulcrum in a lever changes the mechanical advantage of the system. When the fulcrum is moved closer to the load, it requires less effort to lift the load but the distance the load moves is reduced. Conversely, when the fulcrum is moved closer to the effort, it requires more effort to lift the load but the load moves a greater distance.
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.
When the fulcrum is further from the load, the lever arm length increases, which requires less force to lift the load. This allows for greater mechanical advantage, making it easier to lift heavier loads.
because In a Type 1 Lever, the pivot (fulcrum) is between the effort and the load. In an off-center type one lever (like a pliers), the load is larger than the effort, but is moved through a smaller distance. Examples of common tools (and other items) that use a type 1 lever include and in a Type 3 Lever, the effort is between the pivot (fulcrum) and the load.
No, a knife is not a 1st class lever. A 1st class lever is a system where the fulcrum is positioned between the effort and the load. In the case of a knife, it typically functions more like a 3rd class lever where the effort is between the fulcrum and the load, such as when cutting through food.
