## Question:

Replace the three forces acting on the plate by a wrench. Specify the magnitude of the force and couple moment for the wrench and the point $P(y, z)$ where its line of action intersects the plate.

Given:

${ F }_{ A }$ = $80$ $Ib\quad a$ = $12$ $ft$

${ F }_{ B }$ = $60$ $Ib\quad b$ = $12$ $ft$

${ F }_{ C }$ = $40$ $Ib$
