A 30-ft tall drop tower is being used to study the shape of water droplets as they fall through air. A camera is to be carried by a cam-operated linkage which will track the droplets motion from the 7-ft to the 9-ft point in its fall (measured from release point at the top of the tower). The drops are released every 0.5 sec. Every drop is to be filmed. Design a cam and follower which will track these droplets, matching their velocities and accelerations in the 1-ft filming window. Consider acceleration due to gravity, g = 32.2 ft/sec2 . Note that the follower is operating between 7-ft to the 9-ft but it follows the water droplets exactly within the 1-ft filming window.
