Excerpt from Machine Design, Vol. 1: Fastenings The main purpose of this book is to present, in compact form for the use of the student and designer, modern American data from the best practice in the branch of Machine Design to which the work refers. The theoretical treatment of the subject has also been given fully, but this has been done for completeness only, since that field has been covered exhaustively by able writers. Scientific analysis and the records of practice are both essential to success in the design of machine members, but neither alone is trustworthy. The former predicts only those stresses which prevail under normal conditions and ignores the overload, the rough handling, or the slight accident which the machine may meet and against which it should not fail. Practical data, on the other hand, show only the proportions which constructors have given in specific cases of stress and service and empirical formulæ founded upon them may give results wide of the mark, if the inherent limitations of these formulæ be exceeded. The problem of design is one whose many elements vary continually in number, character, and magnitude, and, for its solution, theoretical analysis, precedent, and the ripened judgment of the designer are required. Elsewhere acknowledgment has been made of the courtesy of the many officials and companies who have furnished information. The author's thanks are due especially to Rear Admiral George W. Melville, Engineer-in-Chief, U. S. Navy, Professor Philip R. Alger, U. S. Navy, Professor J. Irvin Chaffee, Leo Morgan, Esq., J. M. Allen, Esq., President the Hartford Steam Boiler Inspection and Insurance Company, C. C. Schneider, Esq., Vice President the American Bridge Company, Messrs. William Sellers and Company, the Baldwin Locomotive Works, and the Newport News Shipbuilding and Dry Dock Company. The author desires also to express his deep indebtedness to Stevenson Taylor, Esq., President of Webb's Academy and Vice President of the W. and A. Fletcher Co., whose examination of, and additions to, the text have added materially to the value of this work.
