Two couple forces $F_1=78N$ and $F_2=65N$ act on the frame. Given that $d=6m,=31,a=1m,b=2m,c=3m,$ and $e=3m,$ resolve the forces

into $x$ and $y$ components and compute the moment by using the following methods:

a$)$ Finding the resultant moment of both moment couples.

$M$:$i+j+$

k$)N*m$

b$)$ Summing the moments of all force components about point $B.$

$M_B$:$,N*m$
