Pascal's principle requires that the pressure is everywhere the same inside the balloon at equilibrium.
But examination immediately reveals that there are great differences in wall tension on different parts of the balloon.
The variation is described by Laplace's Law.

If one can feel the ground through another, or they can through you in most cases it’s over
People misunderstand Peng. There is another word with the same sound and only one stroke different that means something like structure or framework and people often think this is what is meant by Peng. If you base your Taiji on this incorrect meaning of Peng then the whole of your Taiji will be incorrect. Peng Jin is over the whole body and it is used to measure the strength and direction of the partners force. But it is incorrect to offer any resistance. It should be so light that the weight of a feather will make it move. It can be described like water which will, with no intention of its own, support equally the weight of a floating leaf or the weight of a floating ship.

Petty jokes aside, I did like your earlier comment: However, when using Jin you can learn to not "lock out" your arms and achieve the same results though a connected structure and a channeling of the ground force to the point required using the intent (Yi). This is "softer"."
This is a better understanding than a locked frame. The point of course, though I know how you love to play stupid and I certainly don't want to take that away from you, is that you should be light and not offer any resistance, then it's easier to take advantage of your frame. So yes, if a high level MMA fighter is dragged down, he or she sucks in tai chi.
