Problem 1 Consider the follower has the following motion characteristics: • Rise to h= 30 mm with a harmonic motion for e=0° to 120°, • Dwell at h= 30 mm for 0= 120° to 0=180°. • Return (fall) to 0 mm with a parabolic motion for 0= 180ºto 0= 300 ° • Dwell at h=0 mm for 0=300ºto 0=360 (a) Fill the following table 0 0 0 30 60 90 120 180 210 240 270 300 360 y (mm) 0 0 (b) Sketch roughly the following diagrams (versus cam angle (6) where 0S 0 < 360): o follower displacement diagrams o follower velocity diagram o follower acceleration diagram, (b) If c=10 rad/s (constant), find the velocity and acceleration at 0-60 and 240° o
