column with an effective length $L_c=20ft$ in all directions, $F_y=50$ksi?$(2\%)$

b$)$ What is the available axial compressive strength of a $W1060$ column with

$L_{cx}=L_{cy}=18ft$ and $F_y=50$ksi $?$ Also, identify if this section is slender or

nonslender column? $(2\%)$

c$)$ What is the nominal flexural and the nominal shear strength of a $28ftW24$

$76$ beam that is continuously braced through the compression flange, assume

$C_b=1$ and $F_y=50$ksi?$(3\%)$

d$)$ Consider a W$1846$ steel beam in flexural with an unbraced length of $12ft,$

what is the failure mode that this beam will experience in flexural, Lp$,$ and Lr$?$
