A rectangular beam 275 mm wide, 500 mm doop is reinforced at the bottom with 3-20-men-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 fo 21 MPa and steel yield strength ty=415 MPa for 20-mm bars and fy275 MPa for 12-mm bars. Calculate the tenale stool 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 0.xxxxxx
