The book entitled "Introductory Solid Mechanics" is aimed to present the topics of first course on Solid Mechanics (Strength of Materials) at undergraduate level in various universities/institutes. The subject matter is presented chapter wise in an easily understandable style, and learning objectives are indicated at the beginning of each chapter. Large number of worked out problems are given in each chapter to enable the readers to grasp the subject effectively. In addition, at the end of each chapter, highlights containing important definitions, concept and formulae are presented followed by short questions and exercise problems. The first chapter of the book presents simple stresses and strains in which the basic concepts of stress and strain are explained with the discussion on elastic properties. The second chapter deals with the compound stresses and strains where the reader is exposed to analytical as well as graphical method of computing the principal and maximum shear stresses and their associated planes. Chapter three is fully devoted to the shear force and bending moment calculation of beams, whereas chapter four presents the bending stress and shear stress in beams due to their bending. The study of slope and deflection of beams is presented in chapter five where various methods of finding the slope and deflection of beams such as double integration method and moment area method are discussed. Chapter six deals with the study of torsion. The torsion formula is derived, and the combined effects of bending and torsion are presented. The last chapter deals with the analysis of thin cylindrical and spherical shells. For more details, please visit https://centralwestpublishing.com
