Please only answer if confident,

Use shigley book for mechanical design. 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. $9-46F=2$kip,$T=15$kip$*in.$

Bending:

Table $9-2$: $A=1\mathrm{.}414hr=1\mathrm{.}414h(1)=4\mathrm{.}442h$ in ${?}^2$

$I_u=r^3=(1{)}^3=3\mathrm{.}142i{n}^3,I=0\mathrm{.}707h(3\mathrm{.}142)=2\mathrm{.}221hi{n}^4$

${}^{\text{'}}=\frac{V}{A}=\frac{2}{4\mathrm{.}442h}=\frac{0\mathrm{.}4502}{h}k$

$({}^{\text{'}\text{'}}{)}_M=\frac{Mr}{\text{I}}=\frac{2(6)(1)}{2\mathrm{.}221h}=\frac{5\mathrm{.}403}{h}k$

Torsion:

Table $9-1$: $,J_u=2r^3=2(1{)}^3=6\mathrm{.}283$ in ${?}^3,J=0\mathrm{.}707h(6\mathrm{.}283)=4\mathrm{.}442$ in ${?}^4$

$({}^{\text{'}\text{'}}{)}_T=\frac{Tr}{J}=\frac{15(1)}{4\mathrm{.}442h}=\frac{3\mathrm{.}377}{h}k$

${}_{\text{m}\text{a}\text{x}}=\sqrt[\phantom{2}]{{}^{\text{'}2}+({}^{\text{'}\text{'}}{)}_M^2+({}^{\text{'}\text{'}}{)}_T^2}=\sqrt[\phantom{2}]{(\frac{0\mathrm{.}4502}{h}{)}^2+(\frac{5\mathrm{.}403}{h}{)}^2+(\frac{3\mathrm{.}377}{h}{)}^2}=\frac{6\mathrm{.}387}{h}k$

Should specify a $\frac{3}{8}$ in weld. Ans. Type of weld

A 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$).$
