A brush is a third-class lever, where the input force is between the fulcrum (pivot point) and the output force (the bristles of the brush). This type of lever increases the speed and distance of the output force, making it easier to sweep or scrub.
A hairbrush is a third-class lever, where the force is applied between the fulcrum (pivot point) and the load (hair being brushed).

An axe is a type of lever known as a class 1 lever. In a class 1 lever, the fulcrum is located between the effort (in this case, your hand on the handle) and the load (the wood being chopped).
Scissors are typically classified as a type of double lever, where the two blades act as the lever arms with the pivot point being the screw that holds them together.
A ladle is a type of lever known as a class 3 lever. In this type of lever, the effort (force applied) is located between the fulcrum (pivot point) and the load (object being lifted). This allows for controlled pouring and scooping of liquids or other substances.

A toothbrush acts as a third-class lever when in use. In this configuration, the effort is applied between the fulcrum (the point where the brush touches the teeth or gums) and the load (the resistance of the plaque and food particles on the teeth). This arrangement allows for a greater range of motion and speed at the brush head, making it effective for cleaning.
Lever: The handle of a hairbrush acts as a lever. When you hold the handle and press the bristles against your hair, you're using the lever principle to exert force and detangle or style your hair. Wheel and Axle: The base of the hairbrush, where the bristles are attached, can be thought of as a wheel and axle. When you move the brush through
tooth brush is not a lever,because it has no fixed fulcrum from which one can separate the load arm and the effort arm.
