$14-11.$ Design by LRFD and ASD maximum size side SMAW fillets welds required to

develop the loads $P_D=70k,P_L=60k$ for an L$64\frac{1}{2},$ using E$70$ electrodes

and $50$ksi steel. The member is connected on the sides of the $6-$in leg and is subject to

alternating loads. $($Ans$.L_1=12\mathrm{.}5$ in$,L_2=6\mathrm{.}5$ in LRFD; $L_1=13\mathrm{.}5$ in$,L_2=7\mathrm{.}0$
