Determine the largest allowable bending moment


Reinforced concrete highway pavement has a depth of 250 mm with 24 mm diameter steel rebars located 180 mm from the top. The rebars are spaced 200 mm apart. Sketch and analyze one segment of this pavement centered on a rebar. For an allowable stress of 9 Mpa for concrete and 120 Mpa for steel, determine the largest allowable bending moment bending moment for a 1 meter wide section of the highway.Assume E=185 Gpa for steel and E=22 GPa for concrete.
