Excerpt from Structural Engineering Strength of Materials
The present volume is the first of a series treating of the theory anti design of structures, embodying the course which the writer has been giving for many years, with amplifications which, it is hoped, will make it a fairly complete treatise for engineers.
Considering the extent of the field, some subjects arc omitted, and others touched upon briefly. Foundations, for instance, though extremely important for the structural engineer, are not discussed. There are several satisfactory treatises oil that subject, and it is more largely a matter of judgment, experience, and practical detail, and less dependent on fundamental principles, than the topics here included.
It was originally intended that this work should comprise two volumes only; but the theory of structures is so intimately connected with that of the strength of materials, of which it is, strictly speaking, a continuation, that it was decided to limit this first volume to the latter subject. There are many excellent works on the strength of materials, but it was necessary for the writer, in order to present the theory of structures in the way that he prefers, to cover a good part of what is usually included in strength of materials; and if the writer's views and methods are of value, it is hoped that this volume will prove attractive and useful to other than structural engineers.
In connection with the strength of materials, it is desirable that the engineer should be familiar with the fundamental properties of the materials themselves, including their principal physical characteristics, and the most important matters connected with their strength. There are several excellent and exhaustive works on the subject of materials, but it has been thought desirable to prepare a briefer one particularly designed to accompany this volume on strength of materials.
Another volume will complete the theory and the design of simple structures of wood, metal, and masonry; and a final volume will treat of more complicated and statically indeterminate structures.
The first two volumes, namely the present volume on strength of materials, and the one on the fundamental properties of materials, are completed; the last two are well on the way to completion.
The aim of the present volume is to give a complete, clear, and simple discussion of the fundamental principles of the strength of materials applicable in the design of structures of various kinds, not merely of framed structures but of those of masonry and concrete also.
It Is believed to contain all that is needed for machine design also, and so is suited for any student of engineering.
Some books on this subject are so brief that they do not serve as a foundation for further study, while others arc so encyclopedic that the principles are likely to be obscured by a mass of detail.
