$(3)$ Problem $6,$ Chapter $10$

The elliptical section of a column detailed in Figure $10\mathrm{.}13(5)$ is governed by the equation

$(\frac{x}{300}{)}^2+(\frac{y}{150}{)}^2=1$

For the specified eccentricity, obtain the ultimate load $(N_5)$ using the semi$-$graphical pro cedure. Take $f_c^{\text{'}}=50$MPa and a main reinforcement consisting of eight N$2$K bars
