y 20° #2 250 mm С 500 mm B M = 25i (Num) 500 mm A homogeneous 4-kg thin disk is mounted on a horizontal shaft AB. The plane of the disk forms a 20° with the yz plane. The shaft is initially at rest (w = 0) when a moment M is applied to the shaft. Find (a) the resulting angular acceleration of the disk, and (b) the dynamic reactions at A and B immediately after the moment is applied. Neglect the mass of the shaft.
