(a) Figure P8-2 shows the cam and follower. Using graphical methods, find and sketch the equivalent four-bar linkage for this position of the cam and follower. follower arm 3 cam 2 002 Figure P8-2: the cam and follower (b) Design a single-dwell cam to move a follower from 0 to 2.0 inches at 60 deg, fall 2.0 inches at 90 deg and dwell for the remainder. The total cycle must take 2 sec. Choose suitable programs for rise and fall to minimize velocities. Plot the SVAJ diagrams.
