Question: Diagram: (A) Angular velocity of BC: (B) Acceleration of B: (C) Using values from step (A) and (B) to obtain expression for the acceleration of C: The angular acceleration of BC is still unknown, so must find another equation.

(D) Velocity of C and then angular velocity of CD: (E) Using angular velocity from step (D) to obtain ANOTHER expression for the acceleration of C: (F) Equate expressions for the acceleration of C from steps (C) and (E) to find unknowns and finally calculate the value of the acceleration of C. ###### Solution by an expert tutor
