The vertical plane containing the utility cable turns 28° at the vertical pole OC. The tensions T₁ and T₂ are both 815 N. In order to prevent long-term leaning of the pole, guy wires AD and BE are utilized. If the two guy wires are adjusted so as to carry equal tensions T which together reduce the moment at O to zero, determine the net horizontal reaction at O. Determine the required value of T. Neglect the weight of the pole.
