Problem #$6$

a$.)$ Compute the yield moment, $M_y,$ using the method of transformed sections. Material strengths are $f_c^{\text{'}}=4000$ psi and $f_y=60$ ksi.

b$.)$ Determine the maximum moment that can be resisted by the section without exceeding a maximum allowable concrete compressive stress of $0\mathrm{.}45f_c^{\text{'}}$ and steel stress of $0\mathrm{.}4f_y.$
