Extracted text: 1000 100 570 650 A + 325 All dimensions are in mm The cross-section at mid-span of a beam at the edge of a slab is shown in the sketch. A portion of the slab is considered as the effective flange width for the beam. The grades of concrete and reinforcing steel are M 25 and Fe 415 respectively. The total area of reinforcing bars (A) is 4000 mm2. At the ultimate limit state, x, denotes the depth of the neutral axis from the top fibre. Treat the section as under-reinforced and flanged (x,> 100 mm). The value of x, (in mm) computed as per the Limit State Method of IS 456:2000 is
