KUZ E Q.3) In the cam mechanism shown, cam rotates 100 and gives a 30 mm parabolic rise to its follower to the right. Then, follower dwells for 20, returns with harmonic motion for 220 and finally dwells for 20 cam rotation. Follower's mass is 10 kg, spring constant is 6000 N/m and preload in the spring is 20 N. (12p) a) Before any computation, draw graphs of follower's displacement, acceleration and force F23, for the 360 cam rotation. Show on the figure, the cam angle that jump may occur first. (8p) b) Calculate the critical cam speed that jump occurs. 3.
