Extracted text: In the design of beams for the limit state of collapse in flexure as per IS: 456-2000, let the maximum strain in concrete be limited to 0.0025, (in place of 0.0035). For this situation, consider a rectangular beam section with breadth as 250 mm, effective depth as 350 mm, area of tensioned steel as 1500 mm2, and characteristic strengths of concrete and steel as 30 MPa and 250 MPa respectively.At the limiting state of collapse in flexure, the force acting on the compression zone of the section is
