This book discusses key topics in strength of materials,emphasizing applications, problem solving, and design of structural members, mechanical devices, and systems. It covers covers basic concepts, design properties of materials, design of members under direct stress, axial deformation and thermal stresses, torsional shear stress and torsional deformation, shearing forces and bending moments in beams, centroids and moments of inertia of areas, stress due to bending, shearing stresses in beams, special cases of combined stresses, the general case of combined stress and Mohr’s circle, beam deflections, statistically indeterminate beams, columns, and pressure vessels.
