A reinforced concrete beam has a width of 280 mm and an effective depth of 520 mm. It is reinforced for tension only with 5-28 mm diameter bars. Material strengths are f’c = 21 MPa and fs = 128 MPa. Assume n = 9 and use working stress design. What is the location of the neutral axis from the extreme compression fiber of the concrete and the moment capacity of the beam?
