Two uniform disks are made from the same material and have equal masses. The radius RR of disk BB is 7 times larger than the radius rr of disk AA. The disks touch each other and rotate at constant angular speed without skidding. (Figure 1)

Determine the ratio of the disks' thicknesses dA/dB.

Determine the ratio of the disks' angular velocities A/B.A/B.Express your answer as an integer.

Determine the ratio of the disks' rotational inertias IB/IA.

Determine the ratio of the disks' rotational momenta LB/LA.
