This is a clear and thorough guide, with a strong problem solving methodology. In this 6th edition of "Mechanics of Materials", Riley, Sturges, and Morris continue to provide a clear and thorough treatment of stress, strain, and stress strain relationships, as well as axial loading, torsion, flexure, and buckling. Throughout the text, they emphasize fundamental principles, with numerous applications to demonstrate and develop logical, orderly methods of analysis. The authors equip students with an effective problem solving methodology. They encourage students to draw free body diagrams whenever they write an equation of equilibrium, reduce problems to a series of simpler component problems, and present results in a clear manner. Now revised, this Sixth Edition features many new examples and homework problems, a consistent sign convention for internal forces, expanded and improved discussion of the stress element, and new sections on combined loading. New MecMovies promote visualization - Winner of the Premier Award for Excellence in Engineering Education Software, MecMovies, by Tim Philpott of University of Missouri, is a series of interactive tutorials, quizzes, problems, and games to support lectures and self study. Icons in the margins of the text direct readers to appropriate sections of MecMovies. You can access MecMovies through the book's companion website.
