Question

Q3. The homogeneous bar ABC in Fig. Q3 is 3 m long and has a mass of 20 kg. It is pinned to the ground at A and to the

homogeneous bar CD, which is 2 m long with a mass of 10 kg. Determine the angular acceleration of each bar immediately after a restraining wire at C is cut. Assume no friction as D starts moving to the right on the rollers. Draw the free body diagram.
