When I explain this to a group, I always get a challenge from some engineer that what I am saying is not accurate. And after all, they are the “engineers.” So today I asked Google Gemini to explain it to me…
Q: Can a human hold up a wall that is 20' long and 8' tall when 1.0 PSIG is applied to it?
A: The short answer is absolutely not.
While 1.0 PSIG (Pounds per Square Inch Gauge) sounds like a very small amount of pressure, the problem is the massive surface area it is acting upon. In fluid dynamics and engineering, pressure is a force applied over an area. Because the pressure is applied to every single square inch of that wall, it multiplies incredibly fast."
Here is the breakdown of why a human would be immediately crushed:
