A crane boom is supported as shown. The boom has a mass of 660 kg and the box on the end of the cable has a mass of 98 x 10 kg. Assume that the center of mass for the boom is half way along its 15 meter length. Calculate the tension in the upper (diagonal) cable required to support the crane in equilibrium. The cable angle with the ground is 45 degrees and the boom angle with the ground is 60 degrees.
