yogi he figure below shows three rotating, uniform disks that are coupled by belts. one belt runs around the rims of disks a and c. another belt runs around a central hub on disk a and the rim of disk b. the belts move smoothly without slippage on the rims and hub. disk a has radius r; its hub has radius 0.4400r; disk b has radius 0.2700r; and disk c has radius 1.600r. disks b and c have the same density (mass per unit volume) and thickness. what is the ratio of the magnitude of the angular momentum of disk c to that of disk b?
