Homework Statement:

Determine the required magnitude of force F in the resultant couple
moment on the frame is 200 lb.ft clockwise.
Homework Equations:
 ##\Sigma F_x = \textbf{}2*\frac{4F}{5}##
I have to find resultant for this couples:
My sir resolved given forces into components like this:
He considered Fx couples for sides 3,4,5 triangles:
He wrote resultant force for this above diagram: ##\Sigma F_x = \textbf{}2*\frac{4F}{5}##
