A2
![2. This problem concerns the instantaneous center of rotation. At the instant shown in the figure, link AB has
a clockwise angular velocity of magnitude 15 rad/s.

(a) For the link BC, at the instant shown in the figure, determine the location of the link's instantaneous center
of rotation. You will have to think about how to clearly specify this location.
(b) Based on this instantaneous center of rotation, determine the velocity of point C in the figure. Make sure to
specify both the magnitude (a positive number in m/s) and the direction of this velocity.
(c) Based on your answer to part b, determine the angular velocity of link CD. Make sure to specify the
magnitude of this angular velocity (a positive number in rad/s) and whether this angular velocity is clockwise or
counterclockwise.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdfe4c445-b551-49ed-842d-c747788b14c0%2F0a9cbcc0-86b5-4066-b22c-bf56491a8e56%2Fflrjp01_processed.jpeg&w=3840&q=75)
