In geometry, a cycloid is the curve traced by a point on a circle as it rolls along a straight line without slipping. A cycloid is a specific form of trochoid and is an example of a roulette, a curve generated by a curve rolling on another curve. The cycloid, with the cusps pointing upward, is the curve of fastest … See more The cycloid has been called "The Helen of Geometers" as it caused frequent quarrels among 17th-century mathematicians. Historians of mathematics have proposed several candidates for the discoverer of the cycloid. … See more The arc length S of one arch is given by Another geometric way to calculate the length of the cycloid is to notice that when a wire describing an involute has been completely unwrapped from half an arch, it extends itself along two diameters, a length of 4r. This is … See more Several curves are related to the cycloid. • Trochoid: generalization of a cycloid in which the point tracing the curve may be inside the rolling circle (curtate) or outside (prolate). • Hypocycloid: variant of a cycloid in which a circle rolls on the inside of another circle … See more The involute of the cycloid has exactly the same shape as the cycloid it originates from. This can be visualized as the path traced by the tip of a wire initially lying on a half arch of the … See more Using the above parameterization $${\textstyle x=r(t-\sin t),\ y=r(1-\cos t)}$$, the area under one arch, $${\displaystyle 0\leq t\leq 2\pi ,}$$ is given by: This is three times the area of the rolling circle. See more If a simple pendulum is suspended from the cusp of an inverted cycloid, such that the string is constrained to be tangent to one of its arches, and the pendulum's length L is equal to … See more The cycloidal arch was used by architect Louis Kahn in his design for the Kimbell Art Museum in Fort Worth, Texas. It was also used by Wallace K. Harrison in the design of the Hopkins Center at Dartmouth College in Hanover, New Hampshire. Early research … See more WebOct 1, 2016 · According to cycloidal-pin wheel transmission theory, it is known that the cycloid gear is revolved and rotated under the driving force from the input shaft (crankshaft), as does the turning-arm cylindrical roller bearing between the cycloid gear and the crankshaft.
