17-91.
The slender 12-kg bar has a clockwise angular velocity of
w = 2 rad/s when it is in the position shown. Determine its
angular acceleration and the normal reactions of the smooth
surface A and B at this instant.

17-59. The uniform slender rod has a mass m. If it is
released from rest when 0 = 0°, determine the magnitude
of the reactive force exerted on it by pin B when 0 = 90°.
w/
A uniform rod of mass M and length l can pivot freely
(i.e., we ignore friction) about a hinge attached to a wall,
as in Fig. 8-63. 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 the rod, as shown. [Hint: See
Fig. 8–20g.]
