The document describes a graphical user interface (GUI) wing structural design program created in Matlab that outputs structural calculations, shear flow and center calculations, bending stress concentrations from aerodynamic loading, and uses von Mises failure criteria to determine if failure occurs near stress concentrations. It also mentions a view of the North Fork of the American River in California seen from Steven's Trail, where the author currently lives.
