What is the balanced steel reinforcement (mm²) of the beam if it has a specified compressive strength of 27 MPa and steel yield strength of 299 MPa? The width of the beam is 420 mm and it has an effective depth of 732 mm. Round off only on your final answer. (3 decimal places)

the retaining wall shown is supporting a horizonatl backfill having a unit weight of 18.88 kN/m^3 with an angle of friction of 37 degrees. Coefficient of base friction is 0.45. Foundation soil ultimate bearing capacityis 470 kPa. Unit weight of concrete is 23.6 kN/m^3. Compute the factor of safety against sliding considering passive earth pressure at the toe. Compute the factor of safety against overturning. Compute the factor of safety against bearing capacity failure.
