of itssides in the points 1, 2, 3, and 4 (Prob. 1). Join these points,and draw diagonals. Divide each semi-diagonal into three equalparts and join them (Prob. 10), thus making three completesquares parallel to each other. The corner of each of thesesquares in succession will be the centre of one of… … the form of a cam that will produce a rectilinear riiotion that isequable throughout its length. Let BE represent the amount of rectilinear motion required. xvi CYCLOIDAL CURVES, ETC. 1S3 One-half of BE will give the shortest radius of the cam, and oneand a half times BE the longest radius.
