A 2. A traffic light hangs from a pole as shown in the figure. The uniform aluminum pole AB is 6.50 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 the horizontal cable CD and (b) the horizontal and vertical components of the force exerted by the pivot A on the aluminum pole. The mass of the cable is negligible. 3.80 m 37° 1000
