Preface
This collection of problems results from the demand of students for sup-plementary problems and support in the preparation for examinations.With the present collection ’Engineering Mechanics 2 - Formulas andProblems, Mechanics of Materials’ we provide more additional exercisematerial.
The subject ’Mechanics of Materials’ is commonly taught in the se-cond course of Engineering Mechanics classes at universities. The pro-blems analyzed within these courses use equilibrium conditions and ki-nematic relations in conjunction with constitutive relations. As we wantconcentrate more on basic concepts and solution procedures the focuslies on linear elastic material behavior and the small strain regime. Ho-wever, this covers a wide range of elasto-static problems with relevancyin engineering applications. Special attention is given to structural ele-ments like bars, beams and shafts as well as plane stress and strainsituations.
Following the warning in the first collection, we would like to makethe reader aware that pure reading and trying to comprehend the pre-sented solutions will not provide a deeper understanding of mechanics.Neither does it improve the problem solving skills. Using this collec-tion wisely, one has to try to solve the problems independently. Theproposed solution should only be considered when experiencing majorproblems in solving an exercise.
Obviously this collection cannot substitute a full-scale textbook. Ifnot familiar with the formulae, explanations, or technical terms the rea-der has to consider his or her course material or additional textbookson mechanics of materials. An incomplete list is provided on page IX.
