PREFACE

Оглавление

DURING the past six years, the author has contributed to Carpentry and Building, from time to time, series of articles bearing on the strength of wooden floors and roofs, and answered many questions pertaining to the strength of various forms of construction. These articles were so well received—the numbers containing them being long since exhausted—that it has been deemed wise to collate them in book form. This the author has endeavored to do in such a way as to make them most valuable to the student and builder and also for reference.

A few new tables have been added, and the material divided into chapters, and the tables and engravings numbered consecutively.

In the preparation of the original articles, the author tried to present the matter in the simplest possible manner consistent with accuracy, avoiding algebraic formulas and obtuse or technical language, and this object has been constantly in mind in their revision and arrangement in book form.

This work is therefore purposely very elemental, being designed for those readers who have had only a common school education; nevertheless, it is believed to be as accurate and reliable—as far as it goes—as the author’s more advanced treatises. Those readers who desire more information on these subjects will find it in the author’s “Architect’s and Builder’s Pocket Book” and in the volumes of “Building Construction and Superintendence.” The third volume of the latter work will contain examples of almost every form of trussed-roof construction and a vast amount of information relating to roof-trusses.

For young mechanics and draughtsmen who are taking up the study of these subjects without other assistance, this work, however, will probably be found easier to understand and a valuable preparation for more advanced treatises. In fact, the author hopes that this book will be of practical value to a great many carpenters, both young and old, and result in a more intelligent use of building materials.
