This paper presents various examples of symbolic analysis of mechanical, electrical, and thermal networks. These examples illustrate several ways in which symbolic analysis is particularly beneficial to solving a problem. The examples also lead into how symbolic analysis programs may be improved for better operation in an engineering environment. A network methodology is used for problem analysis within this paper. Instead of free body diagrams, the components will be connected at various nodes like an electrical circuit schematic or thermal network. A library of functions has been written for the Mathematica software package which allows both mechanical and electrical networks to be analyzed. This library serves as both a vehicle for setting up realistic problems and an illustration of how a computer algebra system can be an efficient CAE and programming tool. The emphasis of the paper will be on symbolic analysis in practical applications.
