The 20-lb disk is rigidly attached to the 7-lb bar OA, which is pivoted freely about a horizontal axis through point O. If the system is released from rest in the position shown, determine the angular velocity w of the bar and the magnitude R of the pin reaction at O after the bar has rotated 90° OA = 21"
