Separate the frame from the ground to find $\backslash (\backslash$mathrm$\{$Ay$\},\backslash$mathrm$\{$Gy$\}\backslash ),$ and Gx $.$ Mg will give $\backslash (\backslash$mathrm$\{$Ay$\},\backslash$mathrm$\{$Fx$\}\backslash )$ will give Gx$,$ and Fy or Ma will give Gy$.$

Separate the frame into $3$ pieces $(/-\backslash \backslash )$ and draw on supports, external forces and couple moments.

Using the FBD of the horizontal piece $(-),$ Mb gives Ey and Me gives By

Using the FBD of the left piece $(/),$ Md gives Bx

Using the FBD of the right piece $\backslash ((\backslash$mathrm$\{$N$\},\backslash$mathrm$\{$Md$\}\backslash )$ gives Ex
