A cam should be designed only using uniform rise and fall throughout the cam without any dwell period and rise and fall periods should be same. The follower is making a rise of 40 mm when the shaft is rotated to an angle of 150 degrees. What is the maximum rise in a follower?

(a) 48

(b) 57.5

(c) 62.5

(d) 50

I got this question in an online interview.

This interesting question is from Cam in portion Curves used in Engineering Practice of Engineering Drawing

Best answer
The correct answer is (a) 48

For explanation: Given a cam profile is made throughout without any dwell and also with continuous rise- fall period. So 180 = maximum rise, since uniform the rise or fall follows linear function. (40/150) x 180 = 48 mm.
