Elementary Mechanics of Solids [PDF ebook] 
The Commonwealth and International Library: Structure and Solid Body Mechanics

Elementary Mechanics of Solids presents the three fundamental principles, namely, equilibrium of forces, stress-strain relationship, and geometry and compatibility of deformations. This book discusses the concept of simplifying assumptions about behavior to obtain the simpler engineering solutions. Organized into seven chapters, this book begins with an overview of the theory of elasticity. This text then presents a detailed discussion of biaxial stress and strain systems as well as the generalized stress-strain relationships. Other chapters consider the determination of deflections of straight and curved beams due to shearing and bending action. This book discusses as well the elastic torsion of various thin-walled closed and open sections as well as the shaft of solid circular cross section. The final chapter discusses some cases in which the combined effects of torsion and bending occur. This book is a valuable resource for students who wish to obtain a university degree in engineering, diploma of technology, or higher national certificate.
