The pitfalls of statically determinant design

[Bill in Houston]

Ah, yeah, statically determinant. I remember that now. To set up the problem such that you could solve for the forces, you would end up with goofy looking structures that you would never see in real life, where one end of the beam was held by a pin, and one was on a roller... Oh, except that you would see it in the WTC buildings. Very interesting.
