Solved: The Concrete Beam Is Reinforced With Three 20-mm D ...

The concrete beam is reinforced with three 20-mm diameter steel rods. Assume that the concrete cannot support tensile stress. If the allowable compressive stress for concrete is ( allow)con=12.5MPa and the allowable tensile stress for steel is ( allow)st=220MPa determine the required dimension d so that both the concrete and steel achieve their allowable stress simultaneously.
