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. 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.
