A drum of 200-mm radius is attached to a disk of radius rA = 140 mm. The disk and drum have a combined mass of 5 kg and are suspended by two cords, knowing that the acceleration of point B on the cord is zero, TA = 40 N, and TB = 20 N, determine the combined radius of gyration of the disk and drum.
