Appendix D: Hints and Solutions To Selected Problems
OVERVIEW
In almost any technical field problem solving is an essential part of instruction and self-learning. There are many types of problems, including:
-
Purely numerical substitution and calculation problems
-
Analytical derivation problems in which the desired result is known
-
Analytical derivation problems in which the desired result is unknown
-
Problems whose results are best determined through computer modeling
-
Problems requiring some literature research
Each type of problem has its utility and relevance, and an attempt has been made to provide some of each type in this book. Generally, for calculation problems, solutions are not frequently provided because they are straightforward and are usually intended to familiarize the student with typical values and physical dimensions of parameters and results. Analytical derivation problems for which the result is stated are also not frequently worked-out in detail, because that is often the whole purpose of the problem: to discover the best and most appropriate methodology for solving it. This is also true when the desired result is not indicated, but because such problems give the student even fewer clues to the approach and end result, some assistance is provided here. For computer modeling problems the necessary tools have been provided in Appendix C. Finally, some problems require that the student engage in a literature search to find a helpful approach or a discussion of similar problems. Obviously, the bibliography sections at the end of each chapter are provided for this purpose. Part of the rationale for the this text's approach to selected
