Chapter 9.5, Problem 9.5TYU
A pool cue is a wooden rod of uniform composition and is tapered with a larger diameter at one end than at the other end. Use the parallel-axis theorem to decide whether a pool cue has a larger moment of inertia (i) for an axis through the thicker end and perpendicular to the length of the rod, or (ii) for an axis through the thinner end and perpendicular to the length of the rod.
