A solid disk of mass 1.2 kg, and radius 0.26 meters, rotates around an axis through its center of mass at Point O and supports a 0.210-kg hanging mass(m2) as shown at right. A second solid disk of mass 0.35 kg, and radius 0.13 meters, is attached to the bigger disk while supporting a 0.150-kg hanging mass(m1). The hanging masses are trying to rotate the 2- disk system in opposite directions. What is the magnitude of the angular acceleration of the disks?
