This courseware contains eight MATLAB files for machine design. The objective is to help users visualize the computation process using interactive computer graphics. These MATLAB files respectively calculate principal stresses and the maximum shear stress using Mohr circle, shear force and bending moment of a beam, the critical load of a column buckling, safety factors against static failures, gear geometry factors, and gear dynamic factors. Each MATLAB file has a GUI (Graphical User Interface) with a consistent format to allow users enter input data and retrieve output results. The input boxes are editable, and therefore users can re-enter data for a different computation before quitting. All MATLAB files are linked to one gateway file (index_export.m), and running this file first is a good way to access all MATLAB modules. You will find all the necessary files, zipped together for convenience, below.

System Requirements

The courseware will run on MATLAB 6.5 (R13), which requires Pentium based computer with Microsoft Windows 98, NT, or 2000.

MATLAB Instruction

1. Start MATLAB program.
2. Set the Current Directory to the folder containing these MATLAB files.
3. Right click the file (index_export.m for example) and select Run.
