This is an incredible, interesting and educational application, which was created by an MIT lecturer and professional structural engineer. This professor thought there must be a better way to teach the conceptual understanding (as opposed to didactic instructional learning) of structures. So, instead of graphs, text, paragraphs and tough nomenclature with a bunch of math, this application employs pictures.
The pictures are simple and show pushing and pulling forces, as well as weights and lines, to gradually build tons of everyday structures. You may be shocked to find out how suspension bridges work via example, without having to read a single word. The pictures are simple. Some have animation and some have overlays, in which to thoroughly illustrate the relationship between the forces behind each structure. The app even illustrates, again through pictures and animation alone, how to handle basic problems in structural engineering.
This is a great app for imparting a conceptual, pictorial understanding of physics, buildings and engineering. When coupled with the dry theory of it all, you will have a student who can visualize and truly understand and apply the skills necessary to create basic structures.
Compatible with iPhone, iPod touch, and iPad.
