## Question:

Replace the force system acting on the frame by an equivalent resultant force and specify where the resultant’s line of action intersects member $AB$, measured from point $A$.

Given:

${ F }_{ 1 }$ = $36$ $Ib$

${ F }_{ 2 }$ = $20$ $Ib$

${ F }_{ 3 }$ = $25$ $Ib$

$\theta$ = $30$ $deg$

$a$ = $2$ $ft$

$b$ = $4$ $ft$

$c$ = $3$ $ft$

$d$ = $2$ $ft$
