[问答题]
A uniform rod of mass M and length L can pivot freely (i.e., we kdf)t nrzben, b +4bg218(ki f5cp xdx5adnto+e2 ;0oy upt3.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 an5od.x tpx;tn+ p0eoay3 5d2cugular 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 of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
