The Inclined plane: Great tool for many things!

I know you're all thinking the inclined plane is no big deal. Slide a block up the hill to make a pyramid. Make a wedge to keep a door closed! There is a lot more to it than that. An inclined plane allows the user to lift an object using less force than would be required to move the object directly up. The plane allows the object to rise slowly but steadily. When it was invented, about ten thousand years ago it changed the height and majesty of building we could make.

You probably know that Archimedes advanced the uses for the inclined plane by wrapping one around a cylinder and making a screw! Archimedes Screw allowed water to lifted and run through out an area by way of aqua ducts! Let's hear it for the Inclined Plane another gift to us from the smart people Before the Common Era!
