426 - How do hydraulics work in machinery?

Imagine you have a big water pistol that makes a strong water stream when you squeeze it. Now imagine if instead of water, you used a special liquid that can push hard. That's kind of like how hydraulics work.

In a machine, there are two main parts: a small part that you squeeze (or move) and a big part that you want to move or lift (like a heavy weight). These two parts are connected by tubes filled with that special liquid.

When you squeeze the small part, it makes the liquid in the tube push against the other end. Since the liquid can't be squished much, it transfers all the pushing force to the big part. This makes the big part move or lift!

It's based on the idea that liquids can be squeezed hard, but they can't be squished much. This makes hydraulics strong and useful for machines like bulldozers, cranes, and even car brakes.
