The slender 12-kg bar has a clockwise angular velocity of $\omega$ = 2 rad/s when it is in the position shown Suppose that $L$ = 2.1 m. (Figure 1) Determine its angular acceleration, 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. $\alpha$ = 4.45 $\text{rad/}s^2$ Part B Determine the magnitude of the normal reaction of the smooth surface A at this instant. Express your answer to three significant figures and include the appropriate units. $N_A$ = Part C Determine the magnitude of the normal reaction of the smooth surface B at this instant.
