3. Determine the flexural strength (OMn) and shear strength (oVn) of the given section below. The RC beam is simply supported with the span, 25 ft. Dead load is 2

klf (without beam weight) and live load is 3 klf. The beam web center to center spacing is 12 ft (fc' = 5 ksi and= 60 ksi.): hf (flange thickness) = 3 in (30 points)
