Excerpt from The Graphic Method: By Influence Lines for Bridge and Roof Computations This book exhibits an entirely modem graphical treatment, by the method of influence lines, of simple statically determinate structures such as bridges and roof-trusses, three-hinged arches, cantilevers, and other constructions of the same general class. The simplicity, elegance, and generality of procedures by influence lines and areas afford quick and eminently practical methods of computing stresses in all forms of trusses, whether with straight, curved, or broken outlines and with any single or multiple systems of bracing, whether square or skew, or with any manner of loading whatever. The ease and clearness with which the greatest stresses, both main and counter, in web and chord members, may be determined for any specified system of loading has already brought the treatment into general use in practical structural design. Taken as a whole the method commends itself not only as a simple universal system of analysis, but also as a remarkably labor-saving means of making computations in structural work. Some knowledge of elementary algebraic methods, including the method of moments or sections, is required, but nothing more.
