Question

10.42 I take a book that is 30 cm x 20 cm x 3 cm and is held shut by a rubber band, and I throw it into the air spinning about an axis that is close to the book's shortest symmetry axis at 180 rpm. What Chapter 10 Rotational Motion of Rigid Bodies 414 is the angular frequency of the small oscillations of its axis of rotation? What if I spin it about an axis close to the longest symmetry axis? 3. (1 pt) Taylor 10.42 (I will save you some work and tell you that the three principal moments are 34.1M, 75.8M, and 108M, where M is the mass of the book.) Also please comment on what would happen if you spun it around the intermediate symmetry axis.
