Bar AB is pinned to the fixed support at A, and the pin P is fixed to the disk at radius R. The disk with outer radius Ro rolls without slipping over the horizontal flat surface with angular speed wd and angular acceleration ad in the directions shown. At the instant shown, s=35 in., R;= 8.3 in., Ro= 11 in., and wd=15 rad/s. If ad=30 rad/s at the instant shown, determine the angular velocity and angular acceleration of the bar AB B. ad Ro Ri @d disk The angular velocity of the bar AB is The angular acceleration of the bar AB is 4.56 rad/s. 18.43 rad/s
