2. Determine the theoretical steel areas required for the section shown. The dimensions are limited to the values shown. If compression steel is required, assume it will be placed 70 mm from the compression face. Compressive strength = 28 MPa, steel yield strength=420 MPa and modulus of elasticity of steel = 200,000 MPa. 350 mm 500 mm M₁ = 750 kN.m
