Concrete colums are constructed with reinforcing steel in them to make them stronger and more ductile. the reinforcing bars are designated by size, with the size being the diameter in eights of an inch. for example, a #4 bar is 4/8 inch in diameter. a 11 inch square concrete column is constructed with eight #4 bars. a 5 pound load is applied to this column. the modulus of elasticity of the reinforcing steel is 29x106 psi, while the modulus of elasticity of the concrete is 4.1x106 psi. (area of the concrete= 119.4 in^2)

a. what is the stress in the steel?
