Hello,
I'm currently trying to solve a problem involving hydrostatics, but I'm getting stuck when it comes to drawing the forces in the FBD.
The original problem is here:

This is my attempt at drawing the FBD:

My calculations:
R(water) = 187.3 kN
R(mud) = 644.7 kN
I think that should be correct.
However, once I isolated the joint at the intersection of A,B, and C, there is no way I can get the joint to be in equilibrium. (See the bottom right corner of my FBD).
The same problem occurs at D, where the compression force in member D only goes up vertically, but I also have a horizontal component to the reaction force at D.
What am I doing wrong? Does anyone have any hints/suggestions on how to solve this?
Thanks a lot!
