Design a cam to move a follower from 22 mm height to 15 mm height in 60, fall an additional 15 mm in 90°, rise to 22 mm height in 110 , and dwell for the remainder. Use a harmonic function for the rise and a constant velocity function for the fall. The shaft speed is 250 rpm. A) Create the cutoff pattern for the cam if it were to be cut using a laser. B) If a roller follower with a 20 mm diameter is used, determine the trajectory of the follower for programming in a cnc machine. This roller can also become a cutter and its trajectory can cut the cam. Cutter (roller follower) Laser cutter (knife-edge follower)

Build the following part. Report the volume in mm^3. Assume all dimensions are in mm. A=52 B=19 Your answer should have 0 decimal places needed. Ex: 76,440 10 - 30 B

many hours did the carpenter work on the job? 6. What is the area of a rectangular floor that is 7'-3" long and 4'-2" wide? 7. There are 15 risers in a set of stairs running from the basement to the first floor. Each riser is 7 1/4" high. What is the distance between floors? 8. The distance between two floors is 9'-0 1/2". If 14 risers are to be used in a set of stairs, what is the height of each riser?

If this were to be written how would it look like?
