Simple machines around my home

Simple machines are tools that help make something work easier. Some of the items around my home are things that I would have never considered for simple machines.

This simple machine is an example of a lever.

The blinds leading to my balcony are an example of a pulley. Pulleys help move loads up, down and sideways.

This fork and knife are an example of wedges. They are used to help to push or split things apart.

The gears in my watch are an example of wheel and axle.

The key rings that hold my many keys together is an example of a screw. It is a simple machine made from another simple machine that winds around itself.
