20. A load of 300kN is carried by a short concrete column 275mm275mm in size. The column is reinforced with 6 bars of 20mm diameter. Find the stresses in concrete and steel, if the modulus of elasticity for the steel is 17 times that of concrete. If the stress in concrete is not to exceed 4MPa, find the area of steel required, so that the column may carry a load of 450kN
