I would like to get one thing straight in my mind:
If I fill a balloon let's say with 10 bar of air. Is there a formula that relates the force acting on a point $F(x)$ where $x$ is a point on the balloon to the pressure? Especially, it is actually not quite clear to me if the force that a certain point of the balloon experiences is the same everywhere or whether it is the same for all points?-Clearly the diameter is very different for our balloon, so I do not know. I expect the total force to be $$ F = pA$$ where $A$ is the area of the surface, but I don't know if the pressure at a single point of the surface is the same for every point?
