Throughthe center o oi A draw a horizontal line A-i( parallel to the points of division o, i, 2. 3, etc., erect perpendicularsto 0-16 intersecting A-ib. The point o will be the beginningof the cycloid. From i as a center and with the radius of thegenerating circle describe an arc i i tangent to 0-16. Takewith a pair o* dividers a chord o i from the generating circle,and set off this distance i i from i on the arc. The pointthus laid down will be a point in the cycloid. Pioceed in a.
