The wheel is good reasons elements of the wheel and axle which is amongst the six simple machines. Wheels, along with axles, allow heavy objects being moved easily facilitating movement or transportation while supporting lots, or performing labor in machines. Wheels are likewise used in other purposes, say for example ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are merely in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together while using axles. In order that wheels to rotate, some time ought to apply to the wheel about its axis, either in terms of gravity or by the employment of another external force or torque.The English word wheel derives from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, extended form of the main *kwel- "to revolve, navigate 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, known as "tournettes" or "slow wheels", were known in your Middle East via the 5th millennium BCE (one of the initial examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). These folks built from stone or clay and secured down by having a peg from the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently drank in Mesopotamia by 3500 BCE and perhaps since 4000 BCE, and also oldest surviving example, this was included in Ur (modern day Iraq), dates to approximately 3100 BCE.

The pioneer proof wheeled vehicles appears inside the second half of your 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), therefore the question of which culture originally invented the wheeled vehicle continues unsolved.The first well-dated depiction from the wheeled vehicle (here a wagon — four wheels, two axles) is relating to 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 form of wagon construction (the wheel and axle rotate together, as in Ljubljana Marshes Wheel), and this from the Baden culture in Hungary (axle will never rotate). They are both dated to c. 3200–3000 BCE.In China, the wheel was certainly present while using the adoption of one's chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
