11. Iwo beams, one having square cross section and another circular cross-section, are subjected to the same amount of bending moment. If the cross-sectional area as well as the material of both the beams are same then (A) Maximum bending stress developed in both the beams is the same (B) The circular beam experiences more bending stress than the square one (C) The square beam experiences more bending stress than the circular one (D) As the material is same both the beams will experience same deformation

A concrete beam is reinforced by three steel rods placed as shown. The modulus of elasticity is 3* 106 psi for the concrete and 30 *106 psi for the steel. Using an allowable stress of 1350 psi for the concrete and 20 ksi for the steel, determine the largest permissible positive bending moment in the beam.
