Fluid power

Okay kiddo, do you know what a fluid is? Liquids like water and gases like air are fluids. Now, when we want to do some work like moving heavy things, lifting objects or even crushing things, we need a lot of force. This is where fluid power comes in.

Fluid power uses fluids like oil, water or air to create force, which then helps us do work. One way to explain it is to think of a balloon. When you blow air into a balloon, it becomes bigger and harder. This is because the air is pushing against the walls of the balloon, creating force. In fluid power, we use pumps to push the fluid into a cylinder or pipe, which then creates force.

For example, let’s say you want to lift a heavy load. There is a hydraulic system that can do this for you. A hydraulic system uses oil, which is the fluid, to create force. The oil is pumped into a cylinder, which then pushes a piston to lift the load. The more oil that is pumped in, the higher the load goes.

Another example is a pneumatic system. A pneumatic system uses air as the fluid to create force. When air is compressed, it stores energy that can be used to do work. For example, if you want to crush a can, you can use a pneumatic system. The air is compressed in a cylinder, and when released, it creates force to crush the can.

So, there you have it, kiddo. Fluid power is a way of using fluids like oil or air to create force and help us do work, just like blowing up a balloon to create force. It's pretty cool, right?
