## Question:

Replace the loading on the frame by a single resultant force. Specify where its line of action intersects member $AB$, measured from $A$.

Given:

${ F }_{ 1 }$ = $300$ $Ib\quad M$ = $600$ $Ib.ft$

${ F }_{ 2 }$ = $200$ $Ib\quad a$ = $3$ $ft$

${ F }_{ 3 }$ = $400$ $Ib\quad b$ = $4$ $ft$

${ F }_{ 4 }$ = $200$ $Ib\quad c$ = $2$ $ft$

$\quad\quad\quad\quad\quad$ $d$ = $7$ $ft$
