## Homework Statement

A box shaped vessel, of ##4## compartments and ##80m## lenght, light displacement of ##800## tonnes loads ##200## tonnes in the first compartment and ##200## tonnes in the last compartment. Produce the shearing force diagram and bending moment curve.

## Homework Equations

3. The Attempt at a Solution [/B]

I dont fully understand the problem but here is what i tried to do. I calculated the total mass ##M=m + 200 + 200##

So total mass divided by 4 gives me the buoyant force which acts upward opposing the gravity force. ##M/4 = 300##

I uploaded the image below and got that the shearing force goes to ##-100## in the first and last compartment and ##+100## in the middle two. I dont know if this is true however and of the diagram is correct. Moreso i dont know how to draw a bending moment curve. Anyone have a slightest clue of what i should do here?
