[问答题]
A uniform rod of mass M and length Lk,47escih f)z can pivot freel* xt u8tu 4dnsr3hi3k9y (i.e., we ignore friction) about a hinge attached to a wall, as in Fig. 8–54. The rod is held horizontally and then released. At the moment of release, determine (a) the angular acceleration of the rod, and (b) the linear acceleration of the tip of the rod. Assume that the force of gravity acts at the center o u4 hkrtit93u*dx8n3s f mass of the rod, as shown. [Hint: See Fig. 8–21g.]
