Abcs Of Karaoke On 4 Wheels By Stacey Burt In Central America, Maya invented the wheel. At temples can be seen on stone ornaments as a spoked wheel or gear. How far is from finds, but they used it only in applications that did not allow external loads, as for the wheel to represent their calendar and toys (Karaoke on 4 Wheels). Even in pre-Columbian days they used wheel, even gears, in more or less precision equipment. Cars are but in ancient American cultures has not been established. This is possibly due to lack of appropriate draft animals. The rolling resistance on a firm, dry ground and the sliding resistance in bearings are common to substantially less than the sliding resistance with the use of a loop or of a carriage for transporting a load on dry ground. The abrasion material is also less than in grinding. Fellow with wheel and draft animals were readily available and durable for transportation for loads and people in parts of world. Not until the invention of steam engine and the internal combustion engine, which led to higher transport services and speeds, the wheel were completely in iron and later steel plate welded together designed as rim. The lubricated hub sleeves were replaced by roller bearings. Wheel for low loads were provided in lightweight construction with wire spokes that are biased and loaded on train. The design of wheel was always (later paths and roads) matched to surface to be traversed, and improves the surface corresponding to increased requirements. Steel frost on wooden rim wheel for wheelbarrows, two- or four-wheeled wagons, carts or carriages on farmland, field or boardwalks or cobbled streets or the first commercially operated electric tram in FOTG on rails. The edge of tread was chamfered or rounded. Some faces were so well preserved that smoothing strokes of a tool can be seen. The wheel created from alder wood belonged to a car whose front could not swing. When changing the direction the draft animals dragged the front of car to side until the drawbar pointed in desired direction. In loop but some of load and the design weight to carry, they had an advantage over other means of transport a good off-road capability. When using a sledge and rod loops usually a high sliding resistance was overcome. A transport rollers was possible only on well prepared surface and short distances. Most accurate wheel made of plastic are used in precision engineering for power transmission as well as on switch. The wheel and axle system is used mainly for transport; on the one hand on vehicles other than to force deflection of hoists. Axes are used for carrying loads and therefore stressed mainly by bending; Waves and transmit torques (torsion) are therefore mainly exposed to torque. The roller transport is still used today for special purposes such as the relocation of buildings or extreme loads over short distances. The rotatably mounted wheel, ie infinite rotatable about an axis could be made with stone tools. The potters of Indus are considered the first, the potters wheel in 5th millennium BC. AD. Inserting in ceramics production. The first wagon wheel were single or multi-piece wheel wheel with diameters between 40 and 80 cm, with solid, loose or without hub socket or solid axle (axle holes and square).
