cycloid

1 Figure 1.9 A wheel traveling along a road without slipping; the point on the edge of the wheel traces out a cycloid.

2 It is physically impossible to mill out a concave cycloid, by any means whatever, because at the pitch line its radius of curvature is zero, and a milling cutter must have a sensible diameter.

3 There are connections to be made between some of these displays — even the “Tracks of Galileo” with its allusion to “cycloids” and the rectangular-wheeled trike — that might have also been subtly explored.

4 That curve, called a cycloid, is produced by a point on the circumference of a circle or wheel as it rolls along a straight line.

5 Pascal’s labours on the cycloid may be said to bring to a close his scientific career. 

6 In the first course, there was a shoulder of mutton cut into an equilateral triangle, a piece of beef into a rhomboides, and a pudding into a cycloid. 

7 A spot on the tire of a wheel running on a straight, level road, will describe in the air a series of peculiar arches, called the cycloid.

8 The use of motor speed control, automatic cycloid.

9 Kahn played with natural light in the Fort Worth building, suffused with skylights, reflectors and cycloid barrel vaults.

10 The companion to the cycloid is a curve so named on account of its similarity of construction, form and equation to the common cycloid.

11 Ok, so — so the cycloid, well, I guess it doesn't quite look like what I've drawn.

这是摆线，它跟我画的不大一样。

12 The particles starting from x = 0 describe cycloids, and the greatest distance they can get from the plane is equal to the diameter of the generating circle of the cycloid, i.e. to 2Xm/eH�.

13 Pinhole machining of pin gear housing is one of important procedures in manufacturing cycloid speed reducer.

14 Many other mathematicians have written on the cycloid—Blaise Pascal, W. G. Leibnitz, the Bernoullis, Roger Cotes and others—and so assiduously was it studied that it was sometimes named the “Helen of Geometers.”

15 The model on display in the Museo Galileo allows one to test this result by building two tracks: one shaped like a cycloid, the other shaped like the arc of a circle, for comparison.

16 In brief—distinct grounds, and vivid circular or cycloid figures, of no meaning, are here Median laws.

17 On a map the Canary Islands look like seven irregular fish scales, and of these Grand Canary is a cycloid scale.

18 Cycloid gears gearing have found its wide application because of its advantages.

19 The solution is a cycloid, which is the curve created by a rolling wheel in a circle.

20 For this reason the cycloid is called the tautochrone.

由于这个缘故,摆线又叫做等时曲线.
