![Part A
The 25-lb slender rod has a length of 6 ft. Using a collar of negligible
mass, its end A is confined to move along the smooth circular bar of
radius 3/2 ft. End B rests on the floor, for which the coefficient of
kinetic friction is up = 0.2. The bar is released from rest when 0 = 30°.
(Figure 1)
Determine the angular acceleration of the bar at this instant, measured clockwise.
Express your answer using three significant figures. Enter positive value if the angular acceleration is clockwise and negative value if the angular acceleration
is counterclockwise.
