College was a long time ago for me also, and since my field is electronics, I don't even have any of my ME and structures books left, and don't remember much about it. I don't remember any of the equations, but I use two programs for deflection calculations. The first is BeamBoy which is quick and easy to use, and is freeware. It will do stress and deflection graphs for multiple point or distributed loads, with either simple or cantilever supports. The other is Engineering Power Tools, which does a lot more than just deflections, it has a lot of mechanical, electrical, and HVAC calculators and tables. It is shareware, but the free version will do just about everything except saving the results of calculations. Links for downloading are below.
