If the two supported point are location at the same level. The conductor is cover by ice layer of thickness of 1.5 cm. The wind pressure is 200 N/m2. The weight of one meter of the conductor is 6 N. Let point Dis location at the conductor has a vertical distance of 2 m fas from the upper limit level of the towers. Find the horizontal distance between this point and point o (the middle point between the towers).
