A rectangular concrete beam has b = 300 mm and d = 550 mm. The beam is simply supported over a span of 6 m and is use to carry a uniform dead load of 25 kN/m (including its own weight) and uniform live load of 40 kN/m. Assume fy = 420 MPa and f’c =21 MPa. Determine the following: (a) Maximum tension steel area for singly reinforced condition (b) Required tension steel area in mm². *
