Who is the inventor of the inclined plane?

Answer 1

The inclined plane was used by prehistoric peoples. Though they did not understand it as we do, they knew what could be accomplished with it. In this light, the inclined plane was not "invented" by anyone. Only later as our knowledge of science grew did we come to "tag" this simple machine with the name by which it is now known.

Answer 2

The inventor of the inclined plane is not definitively known, as the concept has existed since ancient times. However, the ancient Greek philosopher Archimedes is often credited with developing the principle of the inclined plane as a simple machine.
