20 Inch Smoothie Wheels - A wheel is a circular component that is intended to rotate by using an axle bearing. The wheel is one of many reasons pieces of the wheel and axle which is amongst the six simple machines. Wheels, along side axles, allow heavy objects to become moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels will be used for other purposes, perhaps ship's wheel, wheel, potter's wheel and flywheel.Common examples are only in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a few minutes is required to apply to the wheel about its axis, either as a result of gravity or by the effective use of another external force or torque.The English word wheel is produced by the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, a longer mode of the root *kwel- "to revolve, move ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, rogues both meaning "circle" or "wheel ".Precursors of wheels, termed "tournettes" or "slow wheels", were known around the Middle East by 5th millennium BCE (one of the primary examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). These were fabricated from stone or clay and secured to the floor using a peg in the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently available in Mesopotamia by 3500 BCE and perchance as early as 4000 BCE, additionally,the oldest surviving example, which was found in Ur (modern day Iraq), dates to approximately 3100 BCE.

The main proof wheeled vehicles appears during the last half with the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), in order that the question which culture originally invented the wheeled vehicle remains unsolved.The first well-dated depiction of the wheeled vehicle (here a wagon — four wheels, two axles) is about the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated in any 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 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 type of wagon construction (the wheel and axle rotate together, what i mean Ljubljana Marshes Wheel), and that also in the Baden culture in Hungary (axle will not rotate). They are both dated to c. 3200–3000 BCE.In China, the wheel was certainly present with all the adoption of one's chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
