$9-19$ to $9-22$ A steel bar of thickness $h,$ to be used as a beam, is welded to a vertical support by two fillet welds as shown in the figure.

$($a$)$ Find the safe bending force $F$ if the allowable shear stress in the welds is ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}\text{.}}$

$($b$)$ In part $a,$ you found a simple expression for $F$ in terms of the allowable shear stress. Find the allowable load if the electrode is E$7010,$ the bar is hot$-$rolled $1020,$ and the support is hot$-$rolled $1015.$
