A concrete slab of 200 mm thickness is used to support a floor live load of 500 Pa, dead load of 2000 Pa, and with a span of 6 m and spacing of 2 m. The slab is rigidly attached to a wide flange made of A36 steel with Fy = 248 MPa, and E = 200 GPa. Allowable bending stress is 0.66 Fy and allowable deflection is L/360. Density of concrete is 24 kN/m³. 1. Which of the following most nearly gives the uniform pressure acting on the flange, in Pa? Take unit weight of concrete to be 24 kN/m³.
