Does anyone know what a 8 inch I beam weighs per foot?
How far will one span un supported. We are looking at a spanning 40
foot in 2 sections with poured post / piller in the middle for support.
2 X 12 floor joists will be attached.

8-inch "W" sections weigh anywhere from 10 lbs/ft up to 67 lbs/ft

The second number (in imperial designations) is the weight in pounds per
linear foot, so a W8x27 is (about) 8 inches deep, and weighs (about) 27
pounds per foot. Similar but different in metric designations.

Yes. Nominal depth x wt/ft. The "W" part is a shape designator. There
are also "S" and "HP" sections. You may also run across older I-shaped
sections with the designation of "WF" or "B".
Metric sections tend to have slightly different profiles -- mostly in the
taper of the flanges and in the fillets where the web and flanges meet.
