The jaw can be considered a simple machine in the sense that it functions like a lever. The jaw acts as a lever arm, with the hinge (the temporomandibular joint) serving as the fulcrum. When muscles contract to close the jaw, they exert force that allows for efficient biting and grinding of food, similar to how a lever amplifies force. However, it's important to note that the jaw's complexity and the involvement of various muscles and anatomical structures also add functional intricacies beyond a basic simple machine.
When you chew your food, your jaw acts like a lever, which is a type of simple machine. The jaw functions as a first-class lever, with the hinge acting as the fulcrum and the muscles exerting force on one end while the food is crushed at the other. This mechanical advantage allows for effective grinding and breaking down of food for digestion.
A complex machine.
A train is not a simple machine.
A fulcrum is a part of a simple machine, the lever. Without the fulcrum what is left of the simple machine can no longer increase the applied force and is no longer a simple machine.
A spade is a simple mechanical (tool) machine.

It is a simple lever mechanism using to hold round objects firmly without slipping, as well as to tighten square, hexagonal nuts or bolts.
A tooth is not a lever. A tooth could be part of the lever formed by the jaw. A tooth could be a wedge.
3 jaw but that is hard because both are good
An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.

The jaw can be considered a type of lever, specifically a class 3 lever, because the effort force (muscles) is located between the fulcrum (jaw joint) and the load (food being bitten). This arrangement allows for increased speed and range of motion when chewing.
A pulley isn't a kind of simple machine, it is a simple machine
