Suppose that the mass of the suspended object E is 100 kg and the mass of the bar AB is 20 kg. Assume that the weight of the bar acts at its midpoint. If the sum of the moments about point A due to the weight of the bar and the forces exerted on the “ball” at B by the three cables BC, BD, and BE is zero, determine the tensions in the cables BC and BD.
