Yes and from my FBD it seems the pressure is different but I think I might be wrong. At a certain point on the green line inside the boundaries, the fluid particle experiences a force equal to the weight of the water above and this is balanced by an equal force from below. Since pressure is...

Hmm. But how would the pressure be equal if the weight of water above is different inside and outside the boundary? Can they not be considered as two separate systems now.

I see. Is that because it would just end up moving until pressure is equalized? What if it was a fixed boundary. Then pressure must be unequal on both sidies right?

I was thinking like a piston in a cylinder.

Do you know where I might be able to find a more complete explanation then? Thank you.

I don't understand how pressure must be constant in all directions to balance out the force? Arent the forces in each direction independent, so that pressure forces in the x direction and y direction and z direction can all be different to each other, as long as they are balanced in that...

Well, there is a net force initially then while m1 deforms but once it's stopped deforming forces are balanced? I think it would be like with a trampoline. If someone stands on the trampoline, there's a net force that causes the ropes to sag downwards when you land from each jump and once the...

I think there is for m1 because it wouldn't deform otherwise.

Hmm. Maybe the fact that it's hollow would change the internal stresses it develops? Not sure.

Ok, thanks for clearing that up for me.
