1. A uniform horizontal beam has a mass of 13.1 kg. As you see below, the cable makes an angle of 45 degrees with a vertical pole. The beam's right end is connected to the light (essentially mass-less) cable making a 45-degree angle with the beam. The beam's left end is hinged at pivot A on the rigid, fixed pole. The left end of the cable is also attached to the pole. See figure. Show all work.
