QUESTION 1 Two slender rods AB and CD are welded at B as shown in the figure. Bis the mid point of CD. If the system is released from rest at the instant shown and is rotating in vertical plane, determine the angular acceleration of the rods, a, and components of the reaction at A for this instant. Given: Figure Q1 MaB = 0.6 kg and mcD = 0.3 kg AB = 0.2 m and CD = 0.1 m %3! QUESTION 2 A composite body consist of a disc and a slender rod R = 0.2 m B 0.12 m are welded together is pushed by the force P = 10 N as shown in Figure Q2. The disc is homogenous with a mass of 2.1 kg and the rod is 2.4 kg. If the body is moving 5 0.36 m rad/s clockwise at the instant shown, determine: C a. the angular acceleration of the body, a b. components of force at A Figure Q2
