This program is written for the TI-82 calculator by Tony Wayne. It calculates the center of pressure location for a SIMPLE model rocket. It utilizes the "Barrowman" equations for the calculation of a model rocket's center of pressure. Each screen is split to include a graphic to show the measurement and a question to be answered.

The software is free and may be distributed freely as long as my name remains in it. If you use the software, please e-mail me by clicking here. If people like it and use it, I'll make the effort to post some more of my software.
