Classic potter's kick-wheel in Erfurt, Germany An electric potter's wheel, with bat (green disk) and throwing bucket. Not shown is a foot pedal used to control the speed of the wheel, similar to a sewing machine. In pottery, a potter's wheel is a machine used in the shaping (known as throwing) of clay into round ceramic ware.
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 than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
In Baltic myth, Saule is the life-affirming sun goddess, whose numinous presence is signed by a wheel or a rosette. She spins the sunbeams. The Baltic connection between the sun and spinning is as old as spindles of the sun-stone, amber, that have been uncovered in burial mounds. Baltic legends as told have absorbed many images from ...
" Gretchen am Spinnrade" (Gretchen at the Spinning Wheel), Op. 2, D 118, is a Lied composed by Franz Schubert using the text from Part One, scene 15 of Johann Wolfgang von Goethe's Faust. With "Gretchen am Spinnrade" and some 600 other songs for voice and piano, Schubert contributed transformatively to the genre of Lied .
The scroll wheel on a mouse has been invented multiple times by different people unaware of the others' work. Other scrolling controls on a mouse, and the use of a wheel for scrolling both precede the combination of wheel and mouse. The earliest known example of the former is the Mighty Mouse prototype developed jointly by NTT, Japan and ETH Zürich, Switzer
Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
