Recall the fundamental law of cam design, which states that the cam function must be continuous through the first and second derivatives of displacement across the entire interval (360 degrees). While this is true for most of the interval, because I set the first 50 degrees to zero for displacement, velocity, and acceleration before using the trend line, there is a small jump in the velocity and acceleration plots at 50 degrees. The jump in the velocity plot is almost negligible, but the jump in the acceleration plot is noticeable. Had I taken measurements in smaller increments around the 50 degree mark, the acceleration curve may be smoother.


Notice that the point of contact distance plot is also overlaid on the velocity (in/rad) plot.
