$($I do not know what else you need$)$ Consider a W$12$X$87$ column of A$992$ steel. $($W$12$x$87,$ Kyy$=3\mathrm{.}07$ inch, Ag$=25\mathrm{.}6$ inch$^2,$ Fy$=50$ksi, E$=29000$ksi$)$

a$)$ Determine if this is a slender or non$-$slender element cross section

b$)$ Calculate the largest effective length in the X and Y directions

c$)$ Calculate the largest slenderness ratio in the X and Y directions

d$)$ Determine the effective slenderness ratio for the column

e$)$ Calculate the available compressive strength of the column using the AISC Specification equations
