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