The wheel is a circular and mechanical element that rotates around an axis. It can be considered a simple machine, and is part of the set called machine elements. It is one of the fundamental inventions in the history of mankind, for its great utility in the production of pottery, and also in land transport, as a fundamental component of machines.
The oldest evidence of the use of the wheel (a pictogram of Sumer, in modern Iraq) dates from 3500 BC. From there, the invention spread rapidly throughout the ancient Western world.
