In preparing this fifth edition of Engineering Materials 1 , I have made some significant changes and additions, while being careful not to alter the essential character of the book.

I have added three new chapters. Chapter 7 is a short introduction to applications of elastic deformation, and covers the essentials of beam bending, buckling, and vibration, together with a brief outline of tensor notation for showing stress and strain in three dimensions. It is useful to have these results available separately, to avoid overloading the reader with new concepts when it comes to the relevant case studies later on. make up a new section on thermal properties, and include case studies on their applications.

I have added a significant number of new Examples and Worked Examples, and broken down some existing Examples into smaller, more incremental parts. The Answers are now moved to the end of the Examples in each chapter. Instead of grading the Examples into different categories of difficulty (always a somewhat arbitrary process), I have tried to make them all equally (and reasonably) doable by any reader who has worked carefully through the text. In many cases, this has meant providing additional information, in Examples, Answers, or Worked Examples.
