## Question:

Replace the force system by a single force resultant and specify its point of application, measured along the $x$ axis from point $P$.

Given:

${ F }_{ 1 }$ = $125$ $Ib\quad a$ = $2$ $ft$

${ F }_{ 2 }$ = $350$ $Ib\quad b$ = $6$ $ft$

${ F }_{ 3 }$ = $850$ $Ib\quad c$ = $3$ $ft$

$\quad \quad \quad\quad\quad\quad d$ = $4$ $ft$
