An extract from Field Testing of Monotube Sign Support Structures, Arizonza DoT, Report Number: FHWA/AZ 85/237, SEP 1985 (152 pgs)

"Abstract
The report presents the results of full-scale tests of actual monotube sign support structures in the field, along with detailed theoretical analyses of the structures and comparisons of the analytical and experimental results. Two structures were tested under actual service conditions: … The same two structures were also analyzed by two and three dimensional finite element modeling, using static as well as dynamic (due to vortex shedding) loads. It was found that the correlation between computed and measured strains was good, especially considering the complexity of the analyses. … Recommendations for design criteria and further studies are made.

The control unit of the data collection group was an HP-41CX calculator. This is a user programmable calculator whose software had been designed to control the data collection activities and a number of arithmetic functions. The calculator has a built-in clock and calendar, making it possible to record the data and time of each reading of the gages. The data were initially stored in the calculator's memory and subsequently transferred to the mass storage unit.
The software used by the HP-41CX was originally written by Geotechnical Engineering and Mining Services, Inc. of Littleton. Colorado. However, it was found necessary to modify portions of the code to better perform the required tasks. A complete listing of this software is given in Appendix A.…
…
The data transfer required that programs be run simultaneously on the HP-41CX and the HP-9836. These are listed in Appendix B."
