The second edition of MECHANICS OF MATERIALS by Pytel and Kiusalaas is a concise examination of the fundamentals of Mechanics of Materials. The book maintains the hallmark organization of the previous edition as well as the time-tested problem solving methodology, which incorporates outlines of procedures and numerous sample problems to help ease students through the transition from theory to problem analysis. Emphasis is placed on giving students the introduction to the field that they need along with the problem-solving skills that will help them in their subsequent studies. This is demonstrated in the text by the presentation of fundamental principles before the introduction of advanced/special topics.
- Now includes the analysis of the torsion of rectangular bars, discussing an important applied problem within engineering design.
- Expanded article on reinforced concrete beams now includes Ultimate Moment Analysis based upon the most recent code of the American Concrete Institute (ACI).
- Revised article on the design of intermediate columns now includes the most recent specifications of the American Institute of Steel Construction (AISC).
- Increased amount of figures to accompany homework problems.
- New and revised sample and homework problems.
- In the derivation of formulas, the authors emphasize the physical situation before implementing mathematics to model the problem.
- Free-body diagrams are used throughout the text to identify unknown quantities and to recognize the number of independent equations.
- Virtually, every article is immediately illustrated by sample problems and homework problems that illustrate the principles and the problem-solving procedure introduced in the article.
- End-of-chapter homework exercises serve as a review of the material covered in the chapter.
- Design-oriented computer problems are included at the end of most chapters, intended to be solved using computer languages such as MathCAD and/or MATLAB.
- The text contains an equal number of problems using SI and US Customary Units.
- Basic equations are summarized inside the back cover of the textbook for easy access.
- Offers concise coverage of all of the required material for a Mechanics of Materials course.
- Covers fundamental concepts – clearly and simply – without clouding students’ understanding with details about special cases.
- Advanced topics are found in later chapters and are not interwoven into the early chapters on the basic theory allowing the core material to be efficiently taught without skipping over topics within chapters.
- The general transformation equation for stress (including Mohr’s Circle) are deferred until Chapter 8, after students have gained experience with the basics of axial, torsional, and bending loads.

The presentation is done very well and topic relations and dependence are kept in mind.
There is more in the book than can possibly be taught in a single course. It is good to have this extra material because students who are interested can study it on their own. It shows what comes next in more advanced studies.
