Russell Hibbeler's Mechanics of Materials features a clear and thorough presentation of theory and applications of the principles of mechanics of materials. Now in its eleventh edition, the text continues to empower students with 1. the Procedure for Analysis feature. This provides students with a logical and orderly method for applying theory. Aiming to help students develop their procedures for solving problems, it guides students to master principles and gain confidence. 2. the Important Points feature. This summarizes the most important concepts in a section into points and highlights the ones that are essential to applying theory while solving problems. 3. an emphasis on free-body diagrams. Specific sections and problems are devoted to drawing free-body diagrams, a skill essential to solving equilibrium problems.
