The total cycle must take 4 sec. Size the cam for a 1-in. radius roller follower considering pressure angle and radius of curvature. Use eccentricity only if necessary to balance these functions. Plot both these functions. Draw the cam profile. Repeat this for a flat-faced follower. Which one would you use?
