This class covers all of the basic topics of mechanics of materials, presented at a level suitable for sophomore and junior engineering students. The principal topics are the analysis and design of structural members subjected to tension, compression, torsion, and bendingincluding such fundamental concepts as stress, strain, elastic behavior, inelastic behavior, and strain energy. Other topics of general interest are the transformations of stress and strain, combined loadings, stress concentrations, deflections of beams, and stability of columns. More specialized topics are thermal effects, dynamic loading, non prismatic members, beams of two materials, shear centers, pressure vessels, and statically indeterminate beams. For completeness and occasional reference, elementary topics such as shear forces, bending moments, centroids, and moments of inertia are also presented.
