A rectangular beam 225 mm wide, 450 mm deep is reinforced at the bottom with 5-16-mm-diameter bars and at the top with 3-12-mm bars. Concrete cover to bar centroid at the top is 80 mm and at the bottom is 70 mm. Use concrete strength rc=21 MPa and steel yield strength fy= 415 MPa for 16-mm bars and fy = 275 MPa for 12-mm bars. Calculate the tensile steel strain simultaneous with concrete strain of 0.003 at ultimate stage when the beam is subject to negative bending. Write your final answer in 5 decimal places in the format 0x000xx points
