649 OF ENGINEERING FOBMULÆ. Construction of the Cycloidal Ccrve. On the line A B, lay off any point 1, 2, 3, 4, &c., draw perpendicular lines at each point, and on each describe circles equal to the generating circle. On the circuni. of the circle at 1 lay off 1 • 1' = A. 1. :: :: :: and so on; the points 1', 2', 3, 4', 5 , are points of the curve. See also another method of forming a cycloid, “ Wave Hues.” Calculation of the Cycloidal Curve. Length of base B = 3’14159 d. Diameter of generating circle d — '31831 B. Area of cycloid = area of generating circle X 3. Length of curve = 4 d.
