A steel bar, area 625 mm^2, is embedded in a block of concrete 100 mm x 100 mm. The length of both the steel bar and concrete block is 300 mm. Assuming a value of 210 kN/mm^2 for Young's Modulus for the steel, and 14 kN/mm^2 for the concrete, determine the load carried by the steel and the load carried by the concrete if the combined section is subject to a compressive load of 5 kN. Assume that there is no slip between the steel and concrete(the strain in both materials is equal) and that the load is applied over the entire cross section.
