Consider a rectangular section with a height of 20" and a width of 12". The strain distribution on

this section features a strain of 0.0015 at the top of the height and a strain of -0.0010 at the bottom

of the height. This section is made out of a linear elastic material with a modulus of elasticity equal

to 12,000 ksi. Determine the effective axial load and moment acting about the gross centroidal axis

and the curvature of the section.
