A simply supported beam is made up of A36 steel with Fy=245 MPa and is laterally unsupported all throughout. Determine the allowable bending stress for a span of 5m. Consider that the beam is a rolled wide-flange section. Use the properties of your designated wide-flange section. (#6) a. Determine the design flexural strength (in MPa).
