A reinforced concrete cantilever beam is shown below. The beam cross section is a rectangle, 12 inches deep by 18 inches wide. Material properties are: - Concrete weight: wt = 150 pcf - Concrete compressive strength: f'c = 4000 psi - Concrete tensile strength: f't= 400 psi - Steel tensile strength: fy = 60 ksi - Stirrup consists of #4 bar - Beam is not exposed to weather or in contact with soil. Calculate the maximum bending moment under the beam self-weight. 10 ft- 8,750 lb-ft 10,250 lb-ft 11,250 lb-ft 11,750 lb-ft 18" BEAM SECTION
