Shoelaces can be considered a type of pulley system. When you tie your shoelaces, you are essentially creating a mechanical advantage by wrapping the lace around the shoe's eyelets, allowing you to apply force over a longer distance with less effort. This is similar to how a pulley works, where a rope is wrapped around a wheel to lift heavy objects.

Shoelaces and the holes they are threaded through represent a pulley system simple machine known as a mechanical advantage. By pulling on the shoelaces, you can control the tension, allowing you to tighten or loosen the shoes easily.
Shoelaces are not considered a simple machine. Simple machines are basic mechanical devices that help make work easier, such as levers, pulleys, or inclined planes. Shoelaces are more accurately classified as a fastening or tying mechanism rather than a simple machine.

A shoelace threaded through the eyelets of a shoe can be considered as a pulley system.
A simple machine that helps you tighten shoelaces is a pulley. When you pull on the laces, they wrap around a small wheel, allowing you to apply force more effectively to tighten them. This mechanism makes it easier to secure the laces without having to exert as much effort directly.
Take them out of the shoe and you can put them in the washing machine.

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.
A pulley isn't a kind of simple machine, it is a simple machine
