Design a double-dwell cam to move a follower from 0 to 2.5 in.in 60°, dwell for 120°, fall 2.5 in. in 30°, and dwell for theremainder. The total cycle must take 4 sec. Size the cam for a1-in. radius roller follower considering pressure angle and radiusof curvature. Use eccentricity only if necessary to balance thesefunctions. Plot both these functions. Draw the cam profile. Repeatthis for a flat-faced follower. Which one would you use?
