The spinner on automobile wheels historically refers to knock-off hub nuts or center caps. They may be the actual, or intended to simulate, the design used on antique vehicles or vintage sports cars. A "spinner wheel" in contemporary usage is a type of hubcap or inner wheel ornament, that spins independently inside of a wheel itself when the ...
The spinning drive wheel turns the flyer and, via friction with the flyer shaft, the bobbin. A short tension band, or brake band, adds drag to the bobbin such that when the spinner loosens their tension on the newly spun yarn, the bobbin and flyer spin relative to each other and the yarn is wound onto the bobbin.
The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they ...
Lottery Wheels were introduced in the 1970s and have become a popular method of playing. Several "spin off" methods have since become popular, with mixed acceptance. From a mathematical standpoint 'wheeling' has no impact on the expected value of any given ticket. However, playing a lottery wheel impact the win distribution over time.
Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II, who described a wheel (Bhāskara's wheel) that he claimed would run forever. [2] A drawing of a perpetual motion machine appeared in the sketchbook of Villard de Honnecourt, a 13th-century French master mason and architect.
Hand-spinning is still an important skill in many traditional societies. Hobby or small scale artisan spinners spin their own yarn to control specific yarn qualities and produce yarn that is not widely available commercially. Sometimes these yarns are made available to non-spinners online and in local yarn stores.
A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings.
Video of a spinning, patterned paper disc. At a certain speed the sets of spokes appear to slow and rotate in opposite directions. The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly ...
