38. The parallel axis theorem (Eq. 10-36) shows that I increases with h . The phrase “out to the edge of the disk” (in the problem statement) implies that the maximum h in the graph is, in fact, the radius R of the disk. Thus, R = 0.20 m. Now we can examine, say, the h = 0 datum and use the formula for I com (see Table 10-2(c)) for a solid disk, or

Unformatted text preview: (which might be a little better, since this is independent of whether it is really a solid disk) we can the difference between the h = 0 datum and the h = h max = R datum and relate that difference to the parallel axis theorem (thus the difference is M ( h max ) 2 = 0.10 kgm 2 ). In either case, we arrive at M = 2.5 kg....
