This textbook has been written for the engineering students. This textbook covers the essentials of solid mechanics with reference to basic load-bearing members—straight bars, thin-walled cylindrical and spherical pressure vessels, circular shafts, beams undergoing simple bending, and columns. It concisely elucidates the corresponding fundamental assumptions, important equations, and their range of validity without formal derivations. Subsequently, this textbook contains several carefully selected examples to illustrate sequence of steps in the analysis of forces, stresses and displacements, or stability. It further deals with combined loading, stress and strain transformations, energy methods, and failure analysis using commonly employed criteria. This textbook is a handy, yet complete, resource for graduate and postgraduate engineering students. It will also be a ready reference for a practicing engineers or graduate students preparing for an interview or a competitive examination.
