The sixth edition of this book 'A Textbook of Strength of Materials (Mechanics of Solids)' contains twenty six chapters. This edition has been thoroughly revised and made up-to-date. A lagre number of numerical problems from different B.E. degree examinations have b een added with solution at proper places. At the end of each chapter, highlights, theoretical questions and many unsolved numerical problems with answers have been given for the students tgo practice them. Four advanced topics- stresses due to rotation in thin and thick cylinders. bending of curved bars, theories of failures of the materials, and unsymmetrical bending and shear centre have also been added. These chapters have been written in such a simple and easy to follow language that even an average student can understand them easily by self-study. A large number of objective Type Multiple Choice Questions, asked in the most of the competitive examination,have been indorporated in this edition with answers and explanations to make this edition more useful for competitive examinations.
