$3\mathrm{.}3-5$ An L$64\%$ tension member of A$36$ steel is connected to a gusset plate with $1-$inch$-$diameter bolts, as shown in Figure P$3\mathrm{.}3-5.$ It is subjected to the following service loads: dead load $=50$kips, live load $=100$kips, and wind load $=45$kips. Use Equation $3\mathrm{.}1$ for $U$ and determine whether this member is adequate.

a$.$ Use LRFD$.$

b$.$ Use ASD.
