#2: A traffic light hangs from a structure as shown in Fig. 9-60. The uniform aluminum pole AB is 7.5 m long and has a mass of 8.0 kg. The mass of the traffic light is 12.0 kg. Determine the tension in the horizontal massless cable CD, and the vertical and horizontal components of the force exerted by the pivot A on the aluminum pole. Can I just get help on this one? I figured out the rest.
