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 Ꮎ (°) 0 90 120 180 210 240 270 y (mm) 0 30 60 300 360 0 (b) Sketch roughly the following diagrams (versus cam angle (0) where 0 0 < 360): follower displacement diagrams follower velocity diagram o follower acceleration diagram, (b) If w=10 rad/s (constant), find the velocity and acceleration at 0=60° and 240° Problem 2 Design a full return (fall) polynomial cam that satisfies the following boundary conditions (B.C): At 0=0°, y = h, y'= 0,4" = 0 At 0=ß, y = 0, y = 0,4" = 0
