2. A simply supported rectangular concrete beam is to be made from M21 concrete grade and reinforced with steel bar of 345 MPa yield strength. It carries a uniformly distributed load of 12.5 kN/m and has a span of 6 m. Design the beam, assuming that the shape factor is 0.4. The weight density of steel is 77 kN/m3 and that of concrete is 24 kN/m3.
