The wheel has been essential part of human life from very early years of human civilization. The wheel can be best described as a circular object that rotates on a axel bearing. The earliest wheels were known to be wooden disks with a hole in the middle for the axel. The word wheell first camme from an Old English word. In sanskrit, the wheel is called chakra to mean round or circle. It is believed that the wheel first originated around 3500 BC in Mesapotamia(part of modern Iraq) where it was used for chariots. Some argue that it was invented by the Mesapotamians, the Northern Caucasus and Central Europeans. Therefore, the issue of where the wheel originated in still remains a mystery.
The next step in yhe wheel was made by Egyptians 1500 years later than 2000 BC when they used to spokes in their wheels and proudly used them in their chariots while the Greeks have the honour of introduction the cross bar or H-type wheel.
The other significat developments in the evolution of the wheel includes the introduction of wire tension spoke in 1802 when G.F.Bauer obtained a patent for it and the introduction of a new type of tire in 1845 by R.W.Thompson which was improved later by John Dunlop in 1888.
The wheel was one of the technologies which boosted the industrial revolution. Te invention of the wheel has contributed immensely to the development of technology and the most significat being the water wheel, the cog wheel and the spinning wheel. Some of the latest developments of the wheel include the propeller, the jet engine and flywheel and the turbine.
The wheel which Originated so long ago has passed through many stages of development and change and is now presented in very attractive forms. Today, one connot even imagine any mechanism without a wheel, can you?
