$5\mathrm{.}20.$ Compute the service load capacity $P$ for the

welded bracket of the accompanying figure. The

load is $70\%$ live load and $30\%$ dead load. Neglect

the returns at the outer ends of the $C-$shaped weld

configuration. The weld size is $\frac{3}{8}$ in$.$ and E$70$

electrodes are used in the shielded metal arc

process.

Part $($a$)$ is not required.

$($b$)$ Use AISC Manual Table $8-8,$ "Coefficient C

for Eccentrically Loaded Weld Groups."

$($c$)$ Use elastic $($vector$)$ method.
