Now, consider a W $310118$ section made of G $40\mathrm{.}21$ Grade $350W$ steel and do the following:

$($d$)$ State what the letter and two numbers $($including units$)$ in the section designation mean;

$($e$)$ Give the nominal yield stress, $F_y,$ and nominal ultimate stress, $F_u,$ that would be used in

a design scenario;

$($f$)$ If the member is in pure tension exactly and uniformly at the nominal yield stress, what

is the nominal tensile force in the member;

$($g$)$ Assuming the section is made up of three rectangles, each with the widths and

thicknesses $($and overall depth$)$ given in the section data tables in the CISC Handbook,

and with $x$ and $y$ referring to the major and minor principal axes of the cross$-$section

$($consistent with the key diagram shown in the Handbook$),$ calculate the area, A$,$

moments of inertia, $I_x$ and $I_y,$ section moduli, $S_x$ and $S_y,$ radii of gyration, $r_x$ and $r_y,$ and

plastic moduli, $Z_x$ and $Z_y$; and

$($h$)$ Make a table of the values calculated in part $($g$)$ along with the corresponding values

tabulated in the CISC Handbook and give $($at least$)$ one reason why some are different.
