What kind of simple machine is a pencil?

A pencil can be considered a compound machine, as it is made up of multiple simple machines working together. These simple machines include a wedge (the pencil tip for writing), a lever (the pencil body for holding and applying force), and possibly a wheel and axle (if the pencil has an eraser at one end). The combination of these simple machines allows the pencil to perform its function efficiently.


Which part of a pencil is the top?

If there is a rubber at one end that's the top. if the pencil has no markings then whatever end you don't sharpen will be the top.
