Grateful Dead ☮ The Wheel, 1977 More modern descendants of the wheel include the propellerthe jet enginethe flywheel gyroscope and Reich Werden Mit turbine. During the transition between the Neolithic and the Bronze Agethe very earliest wheels were made of wood, with a hole in the core for the axle. The wheel was found in a settlement built on stilts over wetland, indicating that the settlement had some sort of link to dry land. Archived from the original on 3 July Mary Bellis covered inventions and inventors for ThoughtCo for 18 years. The wheel was also a solar symbol for the Ancient Egyptians. C - years old, and belonged to neolithic Linear Pottery culture. A wheel and axle with force applied to create torque at one radius can translate this to a different force at a different radius, also with Another Name For A Donkey different linear velocity.

Rather, it was the combination of the wheel and axle that made early forms of transportation possible, including carts and chariots. The Bronocice pot, a piece of pottery discovered in Poland and dating to at least B.

The evidence suggests that small wagons or carts, likely drawn by cattle, were in use in Central Europe by this time in human history.

The first carts featured wheels and axles that turned together. Wooden pegs were used to fix the sledge so that when it rested on the rollers it did not move.

The axle turned in between the pegs, allowing the axle and wheels to create all the movement. Later, the pegs were replaced with holes carved into the cart frame, and the axle was placed through the holes.

This made it necessary for the larger wheels and thinner axle to be separate pieces. The wheels were attached to both sides of the axle.

Finally, the fixed axle was invented, wherein the axle did not turn but was solidly connected to the cart frame. The wheels were fitted onto the axle in a way that allowed them to freely rotate.

Fixed axles made for stable carts that could turn corners better. By this time the wheel can be considered a complete invention. Following the invention of the wheel, the Sumerians invented the sledge, a device consisting of a flat base mounted on a pair of runners with curved ends.

The sledge was useful for transporting cargo over smooth terrain; however, the Sumerians quickly realized that the device would be more efficient once it was mounted on rollers.

While the basic function of the wheel is unchanged, modern wheels are much different from the simple wooden wheels of the past.

Innovations in materials science have made possible all kinds of tires for bicycles, cars, motorcycles, and trucks—including tires designed for rough terrain, ice, and snow.

While primarily used for transportation, the wheel also has other applications. Watermills, for example, use water wheels—large structures with a series of blades along the rim—to generate hydropower.

In the past, watermills powered textile mills, sawmills, and gristmills. Today, similar structures called turbines are used to generate wind and hydroelectric power.

The spinning wheel is another example of how the wheel can be used. This device, invented in India over 2, years ago, was used to spin thread from natural fibers such as cotton, flax, and wool.

Early wheels were simple wooden disks with a hole for the axle. Some of the earliest wheels were made from horizontal slices of tree trunks.

Because of the uneven structure of wood , a wheel made from a horizontal slice of a tree trunk will tend to be inferior to one made from rounded pieces of longitudinal boards.

The spoked wheel was invented more recently and allowed the construction of lighter and swifter vehicles. The earliest known examples of wooden spoked wheels are in the context of the Sintashta culture , dating to c.

Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater part of three centuries.

They moved deep into the Greek peninsula where they joined with the existing Mediterranean peoples to give rise, eventually, to classical Greece after the breaking of Minoan dominance and consolidations led by pre-classical Sparta and Athens.

The earliest evidence of spoked wheels in China comes from Qinghai , in the form of two wheel hubs from a site dated between and BC.

The wheel's hub is also present. A horse's spine found nearby suggests the wheel may have been part of a horse-drawn cart.

The wheel was found in a settlement built on stilts over wetland, indicating that the settlement had some sort of link to dry land.

The wheel was barely used, with the exception of the Horn of Africa , in Sub-Saharan Africa well into the 19th century but this changed with the arrival of the Europeans.

The spoked wheel was in continued use without major modification until the s, when wire-spoked wheels and pneumatic tires were invented.

Wire spokes are under tension, not compression, making it possible for the wheel to be both stiff and light. Early radially-spoked wire wheels gave rise to tangentially-spoked wire wheels, which were widely used on cars into the late 20th century.

Cast alloy wheels are now more commonly used; forged alloy wheels are used when weight is critical. The invention of the wheel has also been important for technology in general, important applications including the water wheel , the cogwheel see also antikythera mechanism , the spinning wheel , and the astrolabe or torquetum.

More modern descendants of the wheel include the propeller , the jet engine , the flywheel gyroscope and the turbine.

Twentieth-century solid wheel made of wooden boards, bound with a metal wheel rim. Radially - left and tangentially - right wire-spoked wheels, both with pneumatic tires.

Cast alloy wheel on a folding bicycle , with a pneumatic tire. A wheeled vehicle requires much less work to move than simply dragging the same weight.

The low resistance to motion is explained based on the fact that the frictional work done is no longer at the surface the vehicle is traversing, but in the bearings.

In the simplest and oldest case the bearing is just a round hole through which the axle passes a " plain bearing ".

Even with a plain bearing, the frictional work is greatly reduced because:. Additional energy is lost from the wheel-to-road interface.

This is termed rolling resistance which is predominantly a deformation loss. It depends on the nature of the ground, of the material of the wheel, its inflation in the case of a tire, the net torque exerted by the eventual engine, and many other factors.

A wheel can also offer advantages in traversing irregular surfaces if the wheel radius is sufficiently large compared to the irregularities.

The wheel alone is not a machine, but when attached to an axle in conjunction with bearing, it forms the wheel and axle , one of the simple machines.

A driven wheel is an example of a wheel and axle. Wheels pre-date driven wheels by about years, themselves an evolution of using round logs as rollers to move a heavy load—a practice going back in pre-history so far that it has not been dated.

The rim is the "outer edge of a wheel, holding the tire. For example, on a bicycle wheel the rim is a large hoop attached to the outer ends of the spokes of the wheel that holds the tire and tube.

The hub is the center of the wheel, and typically houses a bearing , and is where the spokes meet. A hubless wheel also known as a rim-rider or centerless wheel is a type of wheel with no center hub.

More specifically, the hub is actually almost as big as the wheel itself. The axle is hollow, following the wheel at very close tolerances. A spoke is one of some number of rods radiating from the center of a wheel the hub where the axle connects , connecting the hub with the round traction surface.

The term originally referred to portions of a log which had been split lengthwise into four or six sections. The radial members of a wagon wheel were made by carving a spoke from a log into their finished shape.

A spokeshave is a tool originally developed for this purpose. Eventually, the term spoke was more commonly applied to the finished product of the wheelwright 's work, than to the materials used.

The rims of wire wheels or "wire spoked wheels" are connected to their hubs by wire spokes. Although these wires are generally stiffer than a typical wire rope , they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting applied loads.

Wire wheels are used on most bicycles and still used on many motorcycles. They were invented by aeronautical engineer George Cayley and first used in bicycles by James Starley.

A process of assembling wire wheels is described as wheelbuilding. A tire in American English and Canadian English or tyre in some Commonwealth Nations such as UK, India, South Africa, Australia and New Zealand is a ring-shaped covering that fits around a wheel rim to protect it and enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.

The word itself may be derived from the word "tie," which refers to the outer steel ring part of a wooden cart wheel that ties the wood segments together see Etymology below.

The fundamental materials of modern tires are synthetic rubber , natural rubber , fabric and wire, along with other compound chemicals.

They consist of a tread and a body. The tread provides traction while the body ensures support. Before rubber was invented, the first versions of tires were simply bands of metal that fitted around wooden wheels to prevent wear and tear.

Today, the vast majority of tires are pneumatic inflatable structures , comprising a doughnut-shaped body of cords and wires encased in rubber and generally filled with compressed air to form an inflatable cushion.

Pneumatic tires are used on many types of vehicles, such as cars , bicycles , motorcycles , trucks , earthmovers , and aircraft.

While wheels are very widely used for ground transport, there are alternatives, some of which are suitable for terrain where wheels are ineffective.

Alternative methods for ground transport without wheels include:. The wheel has also become a strong cultural and spiritual metaphor for a cycle or regular repetition see chakra , reincarnation , Yin and Yang among others.

As such and because of the difficult terrain, wheeled vehicles were forbidden in old Tibet. The wheel in ancient China is seen as a symbol of health and strength and utilized by some villages as a tool to predict future health and success.

The diameter of the wheel is indicator of one's future health. The winged wheel is a symbol of progress, seen in many contexts including the coat of arms of Panama , the logo of the Ohio State Highway Patrol and the State Railway of Thailand.

The wheel is also the prominent figure on the flag of India. The wheel in this case represents law dharma. It also appears in the flag of the Romani people , hinting to their nomadic history and their Indian origins.

The introduction of spoked chariot wheels in the Middle Bronze Age appears to have carried somewhat of a prestige.

The sun cross appears to have a significance in Bronze Age religion , replacing the earlier concept of a Solar barge with the more 'modern' and technologically advanced solar chariot.

The wheel was also a solar symbol for the Ancient Egyptians. From Wikipedia, the free encyclopedia. A circular item that rotates about an axle bearing, often used for transport.
