1. (40 points) A double-dwell cam is to move a follower from 0 to 2" in 120°, dwell for 80°, fall in 90 and dwell for the remainder. The total cycle is 5 seconds. Using cycloidal motion for the rise and 3-4-5 polynomial motion for the fall, find the follower displacement corresponding to the cam angle 0 at 90°, 180°,...
