Excerpt from The Mechanical Properties of Wood Although intended primarily as a textbook for students of wood techlogy and forest utilization, this book has been written with the hope that it may also find use as a source of information for others desiring a kwledge of the technical properties of wood. In serving this objective, comprehensive tables presenting fundamental strength and related properties for more than one hundred and fifty American woods as well as tables of recommended basic and working-stress values for structural species have been incorporated in the text. Examples illustrating the derivation and application of stress values are provided. The treatment of certain phases of the text, especially those dealing with factors affecting the strength of wood and with working stresses and the basis for grading rules for structural lumber, has been made as complete as possible in the space available. An attempt has been made to avoid unnecessary technical language and descriptions, so that it may be understood by all those interested in wood. The preparation of this book was suggested by Dean George A. Garratt whose work of the same title, published in 1931, is well kwn in the field of wood techlogy. Although the present publication is based on Garratt's Mechanical Properties of Wood, subsequent developments in timber mechanics and timber engineering and the increase in kwledge relating to the effects of various factors on the properties of wood have necessitated extensive revision. The arrangement and method of treatment of its predecessor are retained, but the presentation of much of the subject matter is entirely new. Part 1 deals with stress and strain relationships of wood, an appreciation of which is essential to an understanding of its mechanical behavior. Much of the discussion in this section is elementary mechanics of materials in general, although it is written with special reference to wood.
