A Texas cockroach first rides at the center of a circular
Chapter 11, Problem 48(choose chapter or problem)
A Texas cockroach first rides at the center of a circular disk that rotates freely like a merry-goround without external torques. o Radial distance The cockroach then walks out to the edge of the disk, at radius R. Figure 11-49 gives the angular speed W of the cockroach-disk system during the walk. The scale on the W axis is set by Wa = 5.0 rad/s and Wb = 6.0 rad/s. When the cockroach is on the edge at radius R, what is the ratio of the bug's rotational inertia to that of the disk, both calculated about the rotation axis?
