20 Inch Smoothie Wheels - A wheel is often a circular ingredient that is intended to rotate by using an axle bearing. The wheel is one of the many different parts of the wheel and axle which is one of the six simple machines. Wheels, together axles, allow heavy objects turn out to be moved easily facilitating movement or transportation while supporting a large quanity, or performing labor in machines. Wheels are usually intended for other purposes, perhaps ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are normally found in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together using axles. For wheels to rotate, some time is required to be applied to the wheel about its axis, either using gravity or by the application 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-, lengthy form of the source *kwel- "to revolve, maneuver around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, warriors both meaning "circle" or "wheel ".Precursors of wheels, identified as "tournettes" or "slow wheels", were known inside the Middle East by 5th millennium BCE (one of the initial examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE). These folks were made from stone or clay and secured to the floor that has a peg inside the center, but required effort to turn. True (freely-spinning) potter's wheels were apparently available in Mesopotamia by 3500 BCE and perhaps around 4000 BCE, and also the oldest surviving example, which was included in Ur (modern day Iraq), dates to approximately 3100 BCE.

The initial proof wheeled vehicles appears inside the lover on the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), and so the question of which culture originally invented the wheeled vehicle is still unsolved.The primary well-dated depiction from the wheeled vehicle (here a wagon — four wheels, two axles) is in 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 already 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 types of wagon construction (the wheel and axle rotate together, as with Ljubljana Marshes Wheel), and this belonging to the Baden culture in Hungary (axle won't rotate). They are dated to c. 3200–3000 BCE.In China, the wheel was certainly present in the adoption in the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
