text: Towers for this purpose are subjected to severe strains caused by the wind pressure on the wires and to angles in the lines which throw strains upon the cross-arms normal thereto; to the breakage of one of the transmission wires on one side of the tower while the others remain unbroken thereby causing longitudinal forces to be applied at right angles to the cross-arms at either end or at the middle thereof or at all three points along the cross-arm, and to the dead weight of the wires and of the ice coatings formed thereon in wintertime.
