4. The flywheel rotates with angular velocity = 2 rad/s and angular acceleration α = 6 rad/s². Determine (a) the motion of the flywheel, rod AB, and rod BC. Then determine the angular acceleration of (b) link AB and (c) link BC at the instant shown. Use: a = 0.4 m, b = 0.5 m, r = 0.3 m, d = 4, and e = 3. (Hint: Use Translating Frames analysis.) a B Motion: 10. Flywheel -> 11. Rod AB-> a 12. Rod BC->
