If I have a soft base (mud or sand) and place 4 rocket balloons (long narrow ones used for twisting into shapes, animals, etc.) all inflated to the same pressure, but each balloon of a different diameter (1", 2", 3" and 4") and place platform (a thin, but rigid sheet of plastic) on top of the balloons the platform will be at an angle; but if I then place a weight (10 pounds) on top of the platform it will level out. What I want to know: is there a different load value on the soft base beneath each of the balloons? Let's say: 20 psi, 40 psi, etc. or will the pressures even out because the elasticity of the balloon or its conformity to the shape of the soft base spread the load in some other way?
