A great engineering internet website to figure out the beam load calculation is found at the Engineer's Edge Solutions By Design website. The website located at http://www.engineersedge.com/beam_calc_menu.shtml and they offer different calculations for specified loads along with the structural beam deflection and stress formula calculators. The pages contain engineering design calculators to
. determine the amount of deflection a beam of know cross section geometry will deflect under the specified load distribution. The modulus of geometry cross section of a beam is used; however the student engineer will need to determine the moment of inertia.
