Excerpt from Stresses in Girder and Roof Trusses, for Both Dead and Live Loads by Simple Multiplication: With Stress Constants for 100 Cases, Part I. Girders, Part II. RoofsTo most practical engineers and draftsmen who have to design girders and roofs, with little time to spare for mathematical investigation and calculation, the majority of the text-books on this subject are too abstruse.In this work an attempt has been made to Simplify the matter by giving stress constants for both dead and live loads, which only require to be multiplied by the panel load to give the maximum stress in any member of a truss, under the conditions which will be found in the text.The Author does not wish to claim originality for the idea of calculating the stresses due to dead and live loads in the terms of a unit panel load, but he trusts it has been put into a practical shape, suitable alike to the wants of Civil and Mechanical Engineers, Architects and Draftsmen. No attempt has been made in any way to go beyond the subject, and the one hundred cases for which stress constants are given, will, it is hoped, be found suitable for every-day practice.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
