Its primary puqpose is to show students by example how to solve various types of problems given at the ends of chapters in the text. Most of the solutions start from definitions or fundamental relationships and the final equation is derived. This technique highlights the fundamentals and at the same time gives students the opportunity to review the mathematical steps required to obtain a solution. The mere plugging of numbers into equations derived in the text is avoided for the most part. We hope students will learn to examine any assumptions that are made in setting up and solving each problem. Problems in this manual were selected by Jearl Walker. Their solutions are the responsibility of the author alone. The author is extremely grateful to Geraldine Osnato, who oversaw this project, and to her capable assistant Aly Rentrop. For their help and encouragement, special thanks go to the good people of Wiley who saw this manual through production. The author is especially thankful for the dedicated work of Karen Christman, who carefully read and coffected an earlier version of this manual. He is also grateful for the encouragement and strong support of his wife, Mary Ellen Christman. J. Richard Christman Professor Emeritus IJ.S. Coast Guard Academy New London, CT 06320
