This paper describes the theory and use of several computer programs that were written to solve certain engineering structural problems encountered in engineering mechanics and strength of materials. With the aid of these programs, much of the busy work will be taken out of finding solutions to these problems. This will enable the instructor and students to delve more deeply into more important engineering areas, such as optimization.

There are four programs described herein. The first, called TRUSS, solves for the forces in the members of a plane truss structure. The second, OPTIM, optimizes a plane truss according to a certain criterion. The third, BEAM, computes and plots the shear, moment, slope, and deflection of a loaded beam. The last program, BUCKL, determines the critical stress of a column. To aid in clarifying the use of these programs, several example problems are included for each. A complete listing of each program is given in the Appendices.
