Problem 3 a Use the displacement diagram in Problem 1 to draw the cam profile for a radial inline knife- edge follower. The base circle radius is 50 mm and the cam is rotating counterclockwise. Determine the pressure angle at 0–60 and 240°.
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= 180º. Return (fall) to 0 mm with a parabolic motion for 0 = 180° to 0= 300° Dwell at h = 0 mm for 0= 300° to @= 360° (a) Fill the following table 00 0 30 90 120 180 210 240 270 y (mm) 0 60 300 360 0 (b) Sketch roughly the following diagrams (versus cam angle (0) where 0< 0 5 360): o follower displacement diagrams follower velocity diagram follower acceleration diagram, 0 (b) If o 10 rad/s (constant), find the velocity and acceleration at 0-60 and 240
