[问答题]
A uniform rod of mass M and len;d.9y sebrsad c:6qw9 gth L can pivot freely (i.e., we2miovi12jga 2 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 of mass of t ai22go 2mvj1ihe rod, as shown. [Hint: See Fig. 8–21g.]
