A slender rod, m,-5 [kg] and L=750 [mm], is welded to the edge of a uniform disk, ma= 18 [kg] andra=380 [mm], as shown in figure below. The assembly swings freely about A in vertical plane. ForceP=300 [N] is applied to the disk as indicated in the figure. At the position shown the assembly has anangular velocity MA=12 [rad/s] in counterclockwise direction.

6: Determine magnitude of the angular acceleration [rad/s*] of the assembly. 7: Determine magnitude of X component of the reaction force [N] at A. :Determine magnitude of Y component of the reaction force [N] at A.
