please only answer if confident, Table $9-4$ Stresses Permitted by the AISC Code for Weld Metal

$*$The factor of safety $n$ has been computed by using the distortion$-$energy theory.

${?}^{}$ Shear stress on base metal should not exceed $0\mathrm{.}40S_y$ of base metal. Type of weld

use shigleys book of mechanical engineeringA vertical column of $1018$ hot$-$rolled steel is $254\mathrm{.}000$ mm wide. An attachment has been designed to the point shown in

the figure. The static load of $88\mathrm{.}960$ kN is applied, and the clearance $a$ of $158\mathrm{.}750$ mm has to be equaled or exceeded.

The attachment is also $1018$ hot$-$rolled steel, to be made from $12\mathrm{.}700$ mm plate with weld$-$on bosses when all dimensions

are known. Specify the weldment $($give the pattern, electrode number, type of weld, length of weld bead, and leg size$).$

Specify also the length $l_1$ for the attachment.

$($Hints: Use Tables A$-20$ for material properties you need and also use any relevant Figure,

chart, table or equation or any other parameter you need to calculate$).$
