$1.[$textbook $16-1]$ A submerged$-$arc complete joint penetration $($CJP$)$ butt weld was made between two sections of A$36$ hot$-$rolled steel plate. The plate is $10-$in wide by $\backslash (1/2\backslash )-$in$-$thick. E$70$ electrode was used. How much tensile load can the assembly withstand across the weld without yielding in either base metal or weld?

Properties for A$36$ are given in Table $16-3,$ reproduced below. Textbook eq$.2\mathrm{.}5$b gives an estimate of ultimate shear strength from $\backslash ($ S$\_\{$u t$\}\backslash )$

Use it to estimate yield strength of the electrode material.
