[问答题]
A uniform rod of massq*f 1* i ds-nc/n:zeqw M and length L can pivot frevl- +dl )zbb heot94dyps-x8qriq, 1/ ely (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 the8l1b+sezo9q4hdqylixb t vd -- rp/,) rod. Assume that the force of gravity acts at the center of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
