Wheels are raised for other purposes, possibly ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are merely in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together by using axles. In order that wheels to rotate, a second must have to be applied to the wheel about its axis, either by gravity or by the use of another external force or torque.The English word wheel comes from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, an expanded way of the source *kwel- "to revolve, move around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, the second both meaning "circle" or "wheel ".Precursors of wheels, named "tournettes" or "slow wheels", were known in your Middle East by the 5th millennium BCE (one of the primary examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

The initial evidence of wheeled vehicles appears within the better half for the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), therefore the question which culture originally invented the wheeled vehicle continues to be unsolved.The first well-dated depiction of any wheeled vehicle (here a wagon — four wheels, two axles) is about the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated inside of a Funnelbeaker culture settlement in southern Poland.The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia (Ljubljana Marshes Wooden Wheel) will now be dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.2 types of early Neolithic European wheel and axle are known; a circumalpine model of wagon construction (the wheel and axle rotate together, like Ljubljana Marshes Wheel), which from the Baden culture in Hungary (axle is not going to rotate). They are both dated to c. 3200–3000 BCE.In China, the wheel was certainly present together with the adoption of this chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
