Question:

Replace the force system acting on the frame by an equivalent resultant force and couple moment acting at point $A$.

Given:

${ F }_{ 1 }$ = $35$ $Ib\quad a$ = $2$ $ft$

${ F }{ 2 }$ = $20$ $Ib\quad b$ = $4$ $ft$

${ F }_{ 3 }$ = $25$ $Ib\quad c$ = $3$ $ft$

$\theta$ = $30$ $deg\quad d$ = $2$ $ft$
