ABSTRACT
It is common experience among engineers that they need to review some old knowledge or learn
something new because what they needed at the moment is not at their fingertips. This chapter may help in such a situation. Within the constraints of a single book on mechanical engineering, it provides overviews of topics with modern perspectives; illustrations of typical applications; modeling to solve problems quantitatively with realistic simplifications; equations and procedures; useful hints and reminders of common errors; trends of relevant material and mechanical system behaviors; and references to additional information.
