first class levers
actually in front of the effort and resistance forces
An oar is a type of Class 3 lever, where the effort (force applied) is between the fulcrum (pivot point) and the resistance (the water the oar pushes against). In this case, the oar handle is the effort, the oar blade acts as the resistance, and the boat acts as the fulcrum.
The human arm can be classified as a third-class lever, where the effort is between the fulcrum (elbow) and the resistance (object being lifted). This type of lever is efficient for providing speed and range of motion, but requires more effort to overcome the resistance.
A fly swatter is a class 1 lever, where the arm (handle) acts as the fulcrum, the load is the resistance of the fly, and the effort is applied by your hand.
The first kind of lever is a class 1 lever, where the fulcrum is located between the effort force and the load. Examples include a seesaw and scissors.
An icetong is a class 2 lever, where the load is in between the fulcrum and the effort. This means that less effort is needed to lift a heavy load.
An oar is a type of Class 3 lever, where the effort (force applied) is between the fulcrum (pivot point) and the resistance (the water the oar pushes against). In this case, the oar handle is the effort, the oar blade acts as the resistance, and the boat acts as the fulcrum.

An egg beater is an example of a third-class lever. In a third-class lever, the effort is between the fulcrum (pivot point) and the load. In the case of an egg beater, the handle is the effort, the center of rotation is the fulcrum, and the blades are the load.
It's a I dont no that why I'm asking Google
tooth brush is not a lever,because it has no fixed fulcrum from which one can separate the load arm and the effort arm.
A stapler is a class 1 lever, where the fulcrum is located at one end, the effort is applied at the other end, and the load is in the middle.
second class lever
A door typically functions as a first-class lever, with the hinges acting as the fulcrum, the door handle as the effort, and the door itself as the load.
A clothespin is a class 1 lever, where the fulcrum is on one end and the effort is applied on the other end to lift or move the load on the third end.
