Calculate the moment of e p1le3hqgt:2wxsza gq93 o19inertia of the array of poiq,w.02ktgr ilg nb6 i3nt objects shown in Fig. 8–43 abou2g0 iwil3t rn6bgk.,qt (a) the vertical axis, $kg \cdot m^2$ (b) the horizontal axis. Assume m=1.8 kg,M=3.1kg 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. $kg \cdot m^2$ (c) About which axis would it be harder to accelerate this array?
