The 15-lb rod is pinned and has an angular velocity of w = 5 rad/s when it is in the horizontal position shown. Determine the rod's angular acceleration and the pin reactions at this instant.
[A]. alpha (11) = 16.1 rad/s2, Ax = 17.47 lb, Ay = 3.75 lb
[B]. alpha (11) = 64.4 rad/s2, Ax = 17.47 lb, Ay = 30.0 lb
[C]. alpha (11) = 16.1 rad/s2, Ax = 17.47 lb, Ay = 15.00 lb
[D]. alpha (11) = 64.4 rad/s2, Ax = 17.47 lb, Ay = 15.00 lb
