## Question:

The pipe assembly is subjected to the action of a wrench at $B$ and a couple at $A$. Determine the magnitude $F$ of the couple forces so that the system can be simplified to a wrench acting at point $C$.

Given:

$a$ = $0.6$ $m$

$b$ = $0.8$ $m$

$c$ = $0.25$ $m$

$d$ = $0.7$ $m$

$e$ = $0.3$ $m$

$f$ = $0.3$ $m$

$g$ = $0.5$ $m$

$h$ = $0.25$ $m$

$P$ = $60$ $N$

$Q$ = $40$ $N$
