ing circle in C. With C as centre, drawthe rolling circle through P, and find N, its point of con-tact with the fixed line or circle. Join PN, and drawPT perpendicular to PN. Then PN is the normal andPT the tangent at P. To determine O, the centre of curvature, draw from Pthe diameter PCQ. For the… … 120. Special cases of cycloidal curves.—There are twospecial cases with which the student should be acquainted. In the first (a) the hypocycloid is a straight line, being adiameter of the fixed circle. This occurs when the diameterof the rolling circle is half that of the fixed circle. In the…
