A singly reinforced beam of dimension 200 x 350 is reinforced with 3-25mm at the bottom. If the concrete has a compressive strength of 17MPa and the steel has a yield strength of 415 MPa, determine if the beam can carry a uniform distributed load of 18 kN/m dead load. The beam has a length of 5m with 40mm concrete clear cover, 10mm enclosed stirrups, and Es = 200 GPa. Use LRFD in the analysis.
