20 Inch Smoothie Wheels - A wheel is actually a circular ingredient that is intended to rotate during an axle bearing. The wheel is one of the primary components of the wheel and axle which is one of the six simple machines. Wheels, along side axles, allow heavy objects to always be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are usually useful for other purposes, for example a ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are only in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. To ensure that wheels to rotate, a short time really should be relevant to the wheel about its axis, either using gravity or by the application 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-, a long-term form of the source *kwel- "to revolve, move about ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, rogues both meaning "circle" or "wheel ".Precursors of wheels, identified as "tournettes" or "slow wheels", were known from the Middle East by 5th millennium BCE (one of the first examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). These people were created from stone or clay and secured to the floor using a peg around the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently in use in Mesopotamia by 3500 BCE and perchance as early as 4000 BCE, along with the oldest surviving example, that is obtained in Ur (modern day Iraq), dates to approximately 3100 BCE.


The best proof wheeled vehicles appears around the other half from the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), so the question of which culture originally invented the wheeled vehicle will be unsolved.The first well-dated depiction on the wheeled vehicle (here a wagon — four wheels, two axles) is at the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated in a very 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) becomes 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 method of wagon construction (the wheel and axle rotate together, as with Ljubljana Marshes Wheel), and that also of 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 in the adoption on the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
