An overhead line conductor is supported at water crossing from two towers, the heights of the supports being 30 and 34.2 m respectively , above the water level , with a horizontal span of 325 m. the conductor weights 8.42 N/m, and its tension is not to exceed 4.44 * 10^4 N. calculate ;
A-clearance between lowest point of conductor and water
B-horizontal distance of this point from lower support.
