For those of you who are familiar with Google's Sketchup (http://sketchup.google.com/), there's now a physics extension for it availible under http://code.google.com/p/sketchyphysics/

The next version promises joints that you can pose, which would enable adjusting the strut lengths. (see http://youtube.com/watch?v=Xay-Gu9lxGc)
