Prove parametric equations trochoid - Mathematics Stack Exchange
网页0. I have to show that the parametric equations of a trochoid are: x = rθ − d sin θ x = r θ − d sin. . θ and y = r − d cos θ y = r − d cos θ. where r is radius and d is the distance between center of the circle and a point P. Can someone please explain this to me?
Finding the point of intersection of the involute profile and ...
网页The involute is drawn with the base curve-involute intersection on the x axis. The two curves aren't in the same rotation space. In order to mirror the curve (across the x axis) into a whole tooth, I'm rotating the trochoid by pi/N radians and the involute by half a tooth (pi/2N) + the angle to the involute curve at the pitch diameter.

Determine max/min speeds of trochoid - Mathematics Stack …
网页First of all, the minimum and maximum speeds depends on the choice of parametrization. An arc length parametrization is the one for which the speed is always 1. Given your parametrization, the velocity vector is. r′(t) = x′(t),y′(t) = a − b cos t, b sin t . and the square of its length, i.e., the square of its speed, is.

calculus - Finding the area under one arch of cycloid
网页2022年1月28日 · The question asks to find the area under one arch of the cycloid: x = a(t − sint), y = a(1 − cost) The solution says that A = ∫2π0 ydx. I'm just confused about how they were able to get this integral. Can someone please explain how to set up this integral? Why is it not ∫ ydy? This is the same as your standard area integral.
A circle rolls along a parabola - Mathematics Stack Exchange
网页The center of the circle is at p(t) + An(t). The arc length of the parabola is ∫ √1 + (2Ct)2dt = (2Ct√4C2t2 + 1 + sinh − 1(2Ct)) / (4C) =: a(t). The position of a marked point on the circle is p(t) + An(t) + Acos(a(t) − a(t0))n(t) + Asin(a(t) − a(t0))v(t) -that's the (rather complicated) curve you're looking for.
