Excerpt from The Elements of Graphic Statics: And of General Graphic Methods This book is an extension of a course of lectures prepared originally by the authors for students of marine and mechanical engineering and naval architecture in their classes at Webb's Academy and Columbia University. Graphical methods have had their widest application in the analysis of the stresses in stationary structures, and therefore the majority of the text-books on this subject have been written for civil engineers. For the use of students of mechanical and marine engineering, and as of possible service to engin eers in those' professions, this book gives a brief review of the principles of graphics and their application both to framed structures and to mechanism. The text has been illustrated fully by diagrams; occasional references have been furnished to sources of additional information; the principles of Applied Mechanics and of Strength of Materials which are involved in graphic processes have been discussed where necessary; and numerous problems have been assigned to test the students' knowledge of the subject.
