Question

The resultant of a system of forces shown in figure is a force of 10 N parallel to given forces through $R$ , where $P R$ equals

(2/5) $R Q$
(3/5) $R Q$
(2/3) $R Q$
(1/2) $R Q$

The correct answer is: (2/3) $R blank Q$

Equating the moments about $R$
$6 cross times P R equals 4 cross times R Q$
$P R equals fraction numerator 4 over denominator 6 end fraction R Q equals fraction numerator 2 over denominator 3 end fraction R Q$
