QUESTION:

(II) Calculate the moment of inertia of the array of point objects shown in Fig. $8-43$ about $(a)$ the vertical axis, and $(b)$ the horizontal axis. Assume $=1.8\ kg$ . $M=3.1\ kg$ , and the objects are wired together by very light, rigid pieces of wire. The array is rectangular and is split through the middle by the horizontal axis. ( $c$ ) About which axis would it be harder to accelerate this array?
