Expert Solution

Step 1 To find moment

Moment about O

$\begin{array}{rcl} M o m e n t a b o u t O \\ M_{O} & = & x F_{y} = 120 \\ M o m e n t a b o u t B \\ M_{B} & = & 90 \\ (6 - x) F_{Y} & = & 90 \\ 6 F_{y} - x F_{y} & = & 90 \\ s u b s t i t u t e x F_{y} & = & 120 \\ 6 F_{y} - 120 & = & 90 \\ 6 F_{y} & = & 210 \\ F_{y =} 35 l b \end{array}$
