Excerpt from Machine Design, Vol. 1: FasteningsThe main purpose of this book is to present, in compact mm 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 pre vail 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 formulae founded upon them may give results wide of the mark, if the inherent limitations of these formula, be exceeded. The problem of design is one whose many elements vary continually in num ber, character, and magnitude, and, for its solution, theoretical analysis, precedent, and the ripened judgment of the designer are required.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
