16 Inch Alcoa Dually Wheels - A wheel is definitely a circular component that is intended to rotate on an axle bearing. The wheel is one of the primary different parts of the wheel and axle which is regarded as the six simple machines. Wheels, jointly with axles, allow heavy objects to remain moved easily facilitating movement or transportation while supporting a large quanity, or performing labor in machines. Wheels will also be for other purposes, for example a ship's wheel, tyre, potter's wheel and flywheel.Common examples are normally found in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together while using axles. To ensure that wheels to rotate, a minute has to apply to the wheel about its axis, either by using gravity or by the use of another external force or torque.The English word wheel proceeds from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, a long-term kind of the foundation of the *kwel- "to revolve, maneuver around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, these both meaning "circle" or "wheel ".Precursors of wheels, called "tournettes" or "slow wheels", were known while in the Middle East through the 5th millennium BCE (one of the earliest examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). These folks manufactured from stone or clay and secured down using a peg while in the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently active in Mesopotamia by 3500 BCE and possibly since 4000 BCE, and also oldest surviving example, that had been located in Ur (modern day Iraq), dates to approximately 3100 BCE.

The most important evidence of wheeled vehicles appears in the other half with the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), so your question of which culture originally invented the wheeled vehicle continues to unsolved.The primary well-dated depiction from the wheeled vehicle (here a wagon — four wheels, two axles) is along the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated in 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) is already dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.2 kinds of early Neolithic European wheel and axle are known; a circumalpine variety of wagon construction (the wheel and axle rotate together, like Ljubljana Marshes Wheel), and therefore with the Baden culture in Hungary (axle won't rotate). They are dated to c. 3200–3000 BCE.In China, the wheel was certainly present with the adoption on the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
