The spoked wheel was invented to allow the construction of lighter and swifter vehicles. The earliest physical evidence for spoked wheels were found in the Sintashta culture, dating to c. 2000 BCE. [1] Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater
Three spoked wheels on an antique tricycle. The spoked wheel was in continued use without major modification until the 1870s, when wire-spoked wheels and pneumatic tires were invented. [40] Pneumatic tires can greatly reduce rolling resistance and improve comfort.
Aviation, aerodynamics, aeronautics, aeronautical engineering. Sir George Cayley,[1] 6th Baronet (27 December 1773 – 15 December 1857) [2] was an English engineer, inventor, and aviator. He is one of the most important people in the history of aeronautics. Many consider him to be the first true scientific aerial investigator and the first ...
Wire wheel. Wire wheels, wire-spoked wheels, tension-spoked wheels, or "suspension" wheels are wheels whose rims connect to their hubs by wire spokes. [1][2][3] Although these wires are considerably stiffer than a similar diameter wire rope, they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting ...
The execution wheel was typically a large wooden spoked wheel, the same as was used on wooden transport carts and carriages (often with iron rim), sometimes purposely modified with a rectangular iron thrust attached and extending blade-like from part of the rim. The primary goal of the first act was the agonizing mutilation of the body, not death.
A very similar wheel symbol also appears in the flag of the Romani people, hinting to their nomadic history. In non-Buddhist cultural contexts, an eight-spoked wheel resembles a traditional ship's wheel. As a nautical emblem, this image is a common sailor tattoo, which may be misidentified as a dharmachakra or vice versa.
Two-wheeled chariots with spoked wheels appear to have been developed around 2000 BC by the Andronovo culture in southern Siberia and Central Asia. At much the same time the first primitive harness enabling horse-haulage was invented. [7] Wheeled transport created the need for better roads.
Diagram of the steering gear of an 18th- to 19th-century sailing ship [3]: 151 Helm of TS Golden Bear. A ship's wheel is composed of eight cylindrical wooden spokes (though sometimes as few as six or as many as ten or twelve depending on the wheel's size and how much force is needed to turn it.) shaped like balusters and all joined at a central wooden hub or nave (sometimes covered with a ...
