A three-ply asphalt felt and gravel roof over 2-in.-thick insulation board is supported by 18-in-deep precast reinforced concrete beams with 3-ft wide flanges. If the insulation weighs 3 lb/ft2 and the asphalt roofing weighs 5.5 lb/ft2, determine the total dead load, per foot of length, each beam must support.
