The link length and value of OZ for some four-bar linkages are defined below: (fixed link = 12 cm, drive link = 5 cm, coupler link = 10 cm, follower link = 8 cm). 1. Draw the linkage to scale and graphically find all possible solutions (both open and cross) for O3 and O4. Analytically, 2. If ω = 2 rad/s (CCW), find the angular velocity for bar 3 and 4. 3. If ω = 5 rad/s (CCW), find the normal and tangential acceleration for link 3.
