The figure below shows a horizontal bar, of length 2.8 m, with forces acting on it. A 30 N force acts at its left end, point 0, in a direction down and to the left, 45 below horizontal. A 25 N force acts at its center, point C, in a direction up and to the right, 30 to the right of vertical. A 10 N force acts at the right end, in a direction down and to the right, 20 below horizontal
