A disc cam mechanism is required for a machine. A part (the follower) is to move upwards 5.0 cm in 0.2 sec, then remain stationary for 0.1 sec, then move downward 3.0 cm in 0.3 sec, and finally return to the original position in 0.2 sec. a) Determine the required rotational speed of the disk cam b) Sketch a suitable displacement diagram.
