Title: Mechanics of Materials
Authors: Madhukar Vable
Some of the features that should help you meet the learning objectives of this book are summarized here briefly.
• A course in statics is a prerequisite for this course. Appendix A reviews the concepts of statics from the perspective of this course. If you had statics a few terms ago, then you may need to review your statics textbook before the brevity of presentation in Appendix A serves you adequately.
If you feel comfortable with your knowledge of statics, then you can assess for yourself what you need to review by using the Statics Review Exams given in Appendix A.
• All internal forces and moments are printed in bold italics. This is to emphasize that the internal forces and moments must be determined by making an imaginary cut, drawing a free-body diagram, and using equilibrium equations or by using methods that are derived from this approach.
• Every chapter starts by listing the major learning objective(s) and a brief description of the motivation for studying the chapter.
• Every chapter ends with Points and Formulas to Remember, a one-page synopsis of non-optional topics. This brings greater focus to the material that must be learned.
• Every Example problem starts with a Plan and ends with Comments, both of which are specially set off to emphasize the importance of these two features. Developing a plan before solving a problem is essential for the development of analysis skills.
Comments are observations deduced from the example, highlighting concepts discussed in the text preceding the example, or observations that suggest the direction of development of concepts in the text following the example.
• Quick Tests with solutions are designed to help you diagnose your understanding of the text material. To get the maxi- mum benefit from these tests, take them only after you feel comfortable with your understanding of the text material.
• After a major topic you will see a box called Consolidate Your Knowledge. It will suggest that you either write a synopsis or derive a formula. Consolidate Your Knowledge is a learning device that is based on the observation that it is easy to follow someone else’s reasoning but significantly more difficult to develop one’s own reasoning.
By deriving a formula with the book closed or by writing a synopsis of the text, you force yourself to think of details you would not otherwise. When you know your material well, writing will be easy and will not take much time.
• Every chapter has at least one module called MoM in Action, describing a triumph or a tragedy in engineering or nature. These modules describe briefly the social impact and the phenomenological explanation of the triumph or tragedy using mechanics of materials concept.
•Every chapter has a section called Concept Connector, where connections of the chapter material to historical development and advanced topics are made. History shows that concepts are not an outcome of linear logical thinking, but rather a struggle in the dark in which mistakes were often made but the perseverance of pioneers has left us with a rich inheritance.
Connection to advanced topics is an extrapolation of the concepts studied. Other reference material that may be helpful in the future can be found in problems labeled “Stretch yourself.”
• Every chapter ends with Chapter Connector, which serves as a connecting link to the topics in subsequent chapters. Of particular importance are chapter connector sections in Chapters 3 and 7, as these are the two links connecting together three major parts of the book.
• A glossary of all the important concepts is given in Appendix C.7 for easy reference.Chapters number are identified and in the chapter the corresponding word is highlighted in bold.
• At the end is a Formula Sheet for easy reference. Only equations of non-optional topics are listed. There are no explanations of the variables or the equations in order to give your instructor the option of permitting the use of the formula sheet in an exam.
