TAILIEUCHUNG - Ebook Strength of materials: Part 1

(BQ) Strength of materials, Part 1, Elementary theory and problems book has a considerable number of new problems were added and answers to many of the old problems inserted. It is hoped with these major changes as well as the innumerable minor changes throughout the entire book that the volume will be not only more complete but also more satisfactory as a textbook in elementary courses in strength of materials. | Strength of Materials Part I Elementary Theory and Problems By s.

LANCASTER PA. PREFACE TO THE SECOND EDITION In preparing the second edition of this volume an effort has been made to adapt the book to the teaching requirements of our engineering schools. With this in view a portion of the material of a more advanced character which was contained in the previous edition of this volume has been removed and will be included in the new edition of the second volume. At the same time some portions of the book which were only briefly discussed in the first edition have been expanded with the intention of making the book easier to read for the beginner. For this reason chapter II dealing with combined stresses has been entirely rewritten. Also the portion of the book dealing with shearing force and bending moment diagrams has been expanded and a considerable amount of material has been added to the discussion of deflection curves by the integration method. A discussion of column theory and its application has been included in chapter VIII since this subject is usually required in undergraduate courses of strength of materials. Several additions .
