3 Review(s)

The subject lays the ground for various Engineering subjects, ranging from Machine Design, Finite-Element Analysis, Theory of Structures, Bio-Mechanics, and Fracture Mechanics. In this book, the topics are broadly divided into two parts: Elementary Strength of Materials and Advanced Strength of Materials, thereby progressing from basic fundamentals to detailed analysis. The first eight chapters deal with basic concepts of strengths of materials such as theories of stress and strain, torsion, deflection and buckling of columns. The remaining chapters deal with the advanced topics such as advanced theories of stress and strain, energy principles, failure theories, theories of curved and continuous beams, unsymmetric or asymmetric bending. Key Features Complete syllabi coverage of all leading universities of various engineering disciplines like mechanical, civil, electrical, aeronautical, chemical, metallurgy. Topics explored and elaborated for both elementary as well as advanced levels. Self-explanatory figures with liberal use of free-body diagrams to aid easy understanding. Well-graded solved examples from easy to difficult levels in each chapter to explain the subjective intricacies and problem-solving tactics. Last 5 years' questions from various university examinations included at the end of all chapters. Model question papers for giving scope of mock tests appended at the end of the book. Appendices including: Deliberation on the topic of area moment of inertia. Summarised results of beam deflections for various beam configurations. Various symbols with their respective units and brief explanation on the various systems of units. Elaboration on the topic of pure bending and quick calculations for area under parabolas. Excellent pedagogy including: 660+ illustrations. 140+ review questions. 230+ solved examples. 260+ unsolved problems. CD material containing: Three useful chapters containing some special topics on leaf springs, beams of composite materials and continuous beams in form of Chapters 17, 18 and 19. History of the subject and its progress through various centuries. Lab manual containing some important experiments with detailed theory and illustrations. Last 10 years’ IES and GATE completely solved questions with explanatory answers.
