A reinforced concrete column 450 mm 450 mm has four steel rods of 25 mm diameter embedded in it. Find the stresses in steel and concrete when the total load on the column is 1000 kN. Take Es = 205 N/mm and Ec= 13.6 kN/mm. (a) 65.501 N/mm and 4.938 N/mm (b) 87.13 N/mm and 4.938 N/mm (c) 65.501 N/mm and 4.345 N/mm (d) 37.13 N/mm and 4.345 N/mm
