Synopses of several papers presented during 1925: Complete copies available in Pamphlet form: Transmission line design: Mechanical design of spans with supports at unequal elevations

The purpose of this paper is to derive a practical method of design, based upon the catenary formulas for spans whose supports are not at the same elevation. Furthermore, it is intended completely to formulate the method for applying it to any cable which is suspended freely or is uniformly loaded, as well as for obtaining its characteristics after the temperature or loading conditions of the cable have changed. This is a companion method to that presented before the Institute in 1917 by Professor F. K. Kirsten. Since certain changes in Professor Kirsten´s original method seemed advisable to assure greater accuracy as well as to simplify calculations, these changed methods have been used in obtaining certain preliminary data needed for the method presented here.
