Halliday, Resnick & Walker — Rotation: Problem Problem_12

Figure 10.10 shows three disks, each with a uniform distribution of mass. The radii \(R\) and masses \(M\) are indicated. Each disk can rotate around its central axis (perpendicular to the disk face and through the center). Rank the disks according to their rotational inertias calculated about their central axes, greatest first. (a) \(R\): 1 m, \(M\): 26 kg (b) \(R\): 2 m, \(M\): 7 kg (c) \(R\): 3 m, \(M\): 3 kg
