The mass of the head of the hammer shown is 10kg and its centroid mass moment of inertia (IG) is equal to 0.004 kg.m. Rod AB has a mass of 5kg and the disk has a mass of 3kg. if the system is initially at rest at the instant shown, find the angular acceleration of the hammer and the reactions at O immediately after the application of M.
