Need solution by using Bresler reciprocal method

11.15 (Biaxial bending) Determine the load capacity, \( P_{n} \), for the column sections shown in Figs. \( 11.32 \) through \( 11.35 \) if \( e_{y}=8 \) in. and \( e_{x}=6 \) ini. using the Bresler reciprocal method. Use \( f_{c}^{\prime}(4 \mathrm{ksi}) \) and \( f_{y}=60 \mathrm{ksi} \). For each problem the values of \( P_{n x}, P_{n y}, P_{n 0}\left(P_{b x}, M_{b x}\right) \), and \( \left(P_{b y}, M_{b y}\right) \) are as follows: a.
