The rotating disc and its connection with rigidity was also an important thought experiment for Albert Einstein in developing general relativity. [4] He referred to it in several publications in 1912, 1916, 1917, 1922 and drew the insight from it, that the geometry of the disc becomes non-Euclidean for a co-rotating observer.
Von Kármán swirling flow is a flow created by a uniformly rotating infinitely long plane disk, named after Theodore von Kármán who solved the problem in 1921. [1] The rotating disk acts as a fluid pump and is used as a model for centrifugal fans or compressors.

A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder) with an electrical polarity that depends on the direction of ...
Most revolving cylinder, axial piston engine designs utilize a fixed, multi-lobed barrel-type cam and rollers on the pistons to control the reciprocating movement of the pistons. [1] The benefit of this approach, versus a conventional crankshaft -and- connecting-rod mechanism, is that the kinematics of the piston motion can be optimized with ...
An engineering drawing of a Wimshurst machine, from Hawkins Electrical Guide Wimshurst machine in operation Quadruple sector-less Wimshurst machine. The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903).
