Two hangers are attached by a string to a vertically mounted pulley system as shown. One disk is bigger than the other, and the disks are attached to each other such that they rotate together. The axle has negligible friction. The mass of the large disk is 1200 grams and the radius is 11 cm. The mass of the small disk is 400 grams and the radius is 4 cm.
