At the instant shown, link CD rotates with an angular velocity of ω = 6 radj s. If it is subjected to a couple moment M = 450 N m, determine the force developed in link AB, the horizontal and vertical component of reaction on pin D, and the angular acceleration of link CD at this instant. The block has a mass of 50 kg and center of mass at G. Neglect the mass of links AB and CD.
