[问答题]
A uniform rod of mass M and length L can pivot free 9fpqbiq4p +x(ly (i.e., we ig4u y/phdd u5g 96*yg.e7jqo lcnore 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, 9u .gyqoec 7j/d56hlgp y4*dudetermine (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 the rod, as shown. [Hint: See Fig. 8–21g.]
