SUMMARY
The discussion focuses on determining the instantaneous center of rotation for a bar AB with a constant angular velocity of 25 rad/s counterclockwise. The user successfully calculated the velocity of point B (Vb) as 507.5j using the equation Va = Vb + Wba x Ra/b. However, they expressed uncertainty about applying the instantaneous center of rotation method to find the required values for the rectangular plate FBDH and point F. Participants in the discussion provided guidance on identifying the motion directions of points B and D to aid in the solution.
