This text provides a clear, comprehensive presentation of both the theory and applications of mechanics of materials. It examines the physical behavior of materials under load, then proceeds to model this behavior to development theory. Stress. Strain. Mechanical Properties of Materials. Axial load. Torsion. Bending. Transverse Shear. Combined Loadings. Stress Transformation. Strain Transformation. Design of Beams and Shafts. Deflections of Beams and Shafts. Buckling of Columns. Energy Methods. For engineers interested in updating their knowledge of mechanics of materials.
