Hello Tony, I reorganized and created a bunch of new beam deflection calculators.  We now have a menu for these types of calculators  at /beam_calc_menu.shtml . Remember that section modulus = I/D or (Moment of Inertia)/(distance from nuetral plane to outer edge). I guess I should leave the links up...

Thanks!  That's them!  My problem is I know the Section Modulus, but don't know the Moment of Inertia.  How would I find the Moment of Inertia if I didn't already know the Section Modulus?  Thanks again!

Section Modulus = I/D or (Moment of Inertia)/(distance from neutral plane to outer edge)or ... Moment of Inertia = Section Modulus * (distance from neutral plane to outer edge). The (distance from neutral plane to outer edge) is normally the distance from the center of the beam to the outer edge of the beam or, 1/2 the thickness of the beam. Remember, the distance is that which is parallel to the applied load. Hope this helps!
