**Explanation of the Diagram:**
The diagram features a circular flywheel with a radius of 6 inches. A connecting rod, labeled AB, extends from the center of the flywheel to point B. The flywheel rotates clockwise at 690 revolutions per minute. The rod AB is shown passing through a pivoted collar at point C.
- The angle θ, where the rod meets the edge of the flywheel, is given as 59°.
- The distance from the flywheel's center to point C, along the horizontal line, is marked as 17 inches.
- The flywheel is depicted with an arrow showing its clockwise rotation.
- Points A, B, and C are marked on the flywheel and rod, with C being the sliding pivot point on rod AB.
The task is to find the angular velocity of rod AB using relative velocity relations and with reference to point D, which coincides with C.
Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
