simple machine
Yes, a knife is considered a simple machine. It is specifically categorized as a wedge, one of the six classic simple machines.
A knife blade is considered a wedge, which is a type of simple machine. When force is applied to the knife blade, it allows for the cutting of materials by separating them along the sharp edge.
A knife is not considered a simple machine because its primary function is to cut or slice by applying force to a sharp edge, rather than transferring or transforming mechanical energy as simple machines do. It does not have any moving parts or internal mechanisms that provide mechanical advantage.
When two or more simple machines work together, they are called a compound machine. Compound machines are systems that combine multiple simple machines to perform more complex tasks or amplify force.
A complex machine is a single machine that performs multiple simple tasks, such as a car engine. A compound machine is a combination of two or more simple machines working together, such as a bicycle which combines a wheel and axle, lever, and pulley. In summary, a complex machine is one machine with multiple functions, while a compound machine is multiple simple machines working together to achieve a task.
A knife is actually a compound machine as it is both a wedge (the cutting edge) and a lever (as it is normally used in cutting things).

its a compound machine
Its a simple machine machine i could see where your coming from thinking it is a compound machine. But i mean it is simple. Now i know a couple stores have compound machine

wedge
compound machine
no
yes
No, its a simple machine.
Anything with more than one simple machine in it is a compound machine. Since Wheelbarrows have both wheel-and-axle(one simple machine) and levers(Another simple machine), the wheelbarrow becomes a compound machine.
