16 Inch Alcoa Dually Wheels - A wheel is actually a circular ingredient that is supposed to rotate when using axle bearing. The wheel is several parts of the wheel and axle which belongs to the six simple machines. Wheels, at the side of axles, allow heavy objects being moved easily facilitating movement or transportation while supporting a large quanity, or performing labor in machines. Wheels can also be used by 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 with the aid of axles. To ensure wheels to rotate, some time really should 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 is from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, a protracted style of the root *kwel- "to revolve, move around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, rogues both meaning "circle" or "wheel ".Precursors of wheels, often known as "tournettes" or "slow wheels", were known on the Middle East through the 5th millennium BCE (one of the initial examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). They were built from stone or clay and secured to the floor by using a peg during the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently being used in Mesopotamia by 3500 BCE and perhaps as early as 4000 BCE, and then the oldest surviving example, this was evident in Ur (modern day Iraq), dates to approximately 3100 BCE.

The very first evidence of wheeled vehicles appears within the other half for the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), hence the question which culture originally invented the wheeled vehicle is still unsolved.The earliest well-dated depiction of any wheeled vehicle (here a wagon — four wheels, two axles) is relating to the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated from 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 now dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.Two types of early Neolithic European wheel and axle are known; a circumalpine kind of wagon construction (the wheel and axle rotate together, for example Ljubljana Marshes Wheel), and also on the Baden culture in Hungary (axle would not 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.
