131 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 (allown2.5 MPa and the allowable tensile stress for steel is (?allow)st-220 MPa, determine the required dimension d so that both the concrete and steel achieve their allowable stress simultaneously. This condition is said to be 'balanced'. Also, compute the corresponding maximum allowable internal moment M that can be applied to the beam....
