Excerpt from Elementary Graphic Statics and the Construction of Trussed Roofs: A Manual of Theory and PracticeA portion of this work appeared in the form of a series of articles on the Construction of Roofs, published in Building. These articles have been carefully revised, and greatly extended by the addition of such matter as appeared necessary to make the work more suitable as a manual for instruction, for private study, or for reference.It now essentially represents the course of study in Graphic Statics, with special application to Trussed Roofs, pursued by the Students in the School of Architecture of this University for several years past, after a trial of the more favorably known text-books treating this subject.The author has always believed. That, so far as possible, the student should receive full instruction in all those branches of the study which he will be required to apply in completely working out a design for a trussed roof, in actual practice.Consequently, to determine the strains acting in the truss members, to calculate the sectional dimensions required for these members, and to arrange the details of the connecting joints, embodying these details in suitable drawings, are all of equal and essential importance, though text-books usually stop with the first, leaving the student to acquire a knowledge of the others as best he may.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
