Additivity principle earlier tests

Illustrative examples and sample problems are used extensively in the text to illustrate the applications of the principles to practical situations. Problems are included at the ends of most of the chapters to give the reader a chance to test the understanding of the material. Practice-session problems, as well as longer design problems of varying degrees of complexity, are included in Appendix C. Suggested recent references are presented as footnotes to show the reader where additional information can be obtained. Earlier references are listed in the first, second, and third editions of this book.
