I've been thinking about the building-design simulation, and am hoping that someone can point me toward more complete treatises/references, than this hobbyist impression. I'm trying to develop a mathematical outline of simulated deformation physics, with the hope of eventually creating a building-design cautions via simulation program and/or plugin (long-term hope). (This is a re-posting since I mixed up torque and Moment-of-inertia...and I'm therefore not sure if I inadvertantly skipped between Force and Mass (F=ma). Please let me know.) Here's what I've been thinking about: If you know of nice references of this, please let me know. Thanks for you consideration.
