A cam is to be used for a platform that will repeatedly lift boxes from a lower conveyor to an upper conveyor as shown in the Figure below. It will go through the following motion sequence in one revolution of the cam: rise 4 inch in 2 second, dwell for 1 second, fall 2 inch in 1 second, dwell for 1 second, fall 2 inch in 1 second. BOU A box lifiting mechanism 1) What is the time of a full cycle? (5 point) What motion sequence it is in when the cam rotated cycle? (5 point) 2) What is the angular velocity of the cam (with units)? (5 points) 3) Plot the s diagram. Use cam angle (degree) as the x-axis and the displacement (inch) as the y-axis. For rise and fall, as the function is not given, just mark the start and end points. (15 points) 4) Assuming the design satisfies the fundamental law of cam design, list the boundary conditions (s,v,a) for the rise function. (5 points) 5) List the boundary conditions (s,v,a) for the first fall function. (5 points)
