21. (II) A traffic light hangs from a pole as shown in Fig. 12-60. The uniform aluminum pole AB is 7.20 m long and has a mass of 12.0 kg. The mass of the traffic light is 21.5 kg. Determine (a) the tension in B the horizontal massless cable CD, and (b) the vertical and hori- zontal components of the force exerted by the pivot A on the aluminum pole.
