Tensile Strength

$3\mathrm{.}2-3$ A C$1230$ is connected with $1-$in$.$ diameter bolts in each flange, as shown in Figure P$3\mathrm{.}2-3.$ If $F_y=50$ksi,$F_u=65$ksi, and $A_e=0\mathrm{.}90A_n,$ compute the following.

a$.$ The design strength for LRFD$.$

$3\mathrm{.}2-5$ The tension member shown in Figure P$3\mathrm{.}2-5$ is a PL $\frac{1}{2}8$ of A$36$ steel. The member is connected to a gusset plate with$-1\frac{\frac{1}{8}}{8}$ inch$-$diameter bolts. It is subjected to the dead and live loads shown. Does this member have enough strength? Assume that $A_e=A_n.$

a$.$ Use LRFD$.$
