Determine the value of maximum principal stress
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.
