Mechanics of materials is concerned with the development of relationships between the loads applied to a non-rigid body, and the internal forces and deformations induced by the body. This book focuses on what materials specifications (type, size, etc.) and design are most effective based on function and actual load-carrying capacity.
A clear and thorough guide, with a strong problem-solving methodologyIn 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.
