That is what computers are for. Doing the idiotic busywork of searching.
People like you can't figure out the important information to search for to resolve the grade school physics problem. Search for "center of gravity" and "center of mass". The NCSTAR1 report says the top of the south tower tilted more than 20 degrees and how much north/south and how much east/west but not where the center of gravity was so we can figure out whether or not it was still above the core.
That is one of the peculiar things about 9/11. Why didn't the top of the south tower crush one side of the building more than the other and fall down the side?
That 10,000 page report is STUPID! Some people are just too dumb to figure out some of the reasons why it is STUPID.

Well, if you can't figure that out I can't see any reason trying to explain it.

Expression of Dead Load in Structural Calculations
There are several convenient ways to express the intensity of dead loads.
Floors, Roofs, and Walls
Most floor, roof, and wall systems have fairly uniform density and their weights can be expressed in terms of weight per unit area. With dead loads expressed in this manner, tributary area concepts can be used to determine the forces exerted on the supporting members.
To compute the average unit weight (i.e. weight per unit area) such a system, the weights of all items in system are expressed in terms of their weight per square foot of surface area even if they are located as particular locations.

Pounds per square inchOneRiot
A pressure gauge reading in psi (red scale) and kPa (black scale)
The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in2 or lbf/in2 or lbf/sq in or lbf/sq in) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch:
1 psi approximately equals 6,894.757 Pa, where pascal (Pa) is the SI unit of pressure.
pounds per square inch (PSI)
Definition
Pressure a gas or liquid exerts on the walls of its container. Also called PSIG for pounds per square inch gauge. See also bar.

Glad you think that you have an "understanding" of physics. Unfortunately it takes a lot more than that to understand a complex event like a massive building collapse.
Things like false flags, espionage, politics, corruption, apartheid, military industry complex, global banking, neo conservationism, zionism, new world order, media consolidation, psychological operations and information warfare also help.

Not that it makes any difference to what psi is.
Yep, since I said pounds per square foot, the defintion for pounds per square inch doesn't make a difference. You do realize that inches and feet are different, right? That they're not the same thing?
Oh Hooper you do have a serious reading comprehension problem. Your quote is talking about 'weight per unit area', that is not 'pounds per square inch', or 'foot'.
The distributions of steel and concrete need to be gotten correct just for skyscrapers to hold themselves up and withstand the wind.
PSI is pounds per square inch, which is pressure, period.
This is typical of you, if you knew anything about physics and mechanics you wouldn't be making this ridiculous claim.

Good Lord! You actually posted my quote wherein I underlined the phrase WEIGHT PER SQUARE FOOT OF SURFACE AREA then proceeded to tell me I have a reading comprehension problem because it doesn't say foot!

Forget it, you're obviously not going to pick up on the obvious difference as all your knowledge is a result of intense study at Google University. Pounds per square foot - PSF - is, in the matter that was being discussed, the distribution of steel and concrete in a building - is a reference to weight per square foot. Try and stay on the point.
You argued PSI was a measurement of weight not pressure, nothing more nothing less.

Please show me where I argued that PSI is a measurement of weight and not pressure. I didn't even mention PSI until you brought it up.

Pound Force Per Square Foot (lbf/ft2) is a unit in the category of Pressure. It is also known as pound force/square foot, pound per square foot. This unit is commonly used in the UK, US, FPS unit systems. Pound Force Per Square Foot (lbf/ft2) has a dimension of ML-1T-2 where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit Pa by multiplying its value by a factor of 47.88025898.
PSF, PSI, both mean PRESSURE, not weight.

Context. When a structural engineer is discussing dead loads and building materials they are talking about the weight of materials (concrete, steel, wood, ceiling tiles, etc.) per square foot as they are generally found in a given area, floor or level of a structure. End of discussion. You don't have a clue.

How to Calculate Pound Per Square Foot Loads
The pound per square foot load, also known as pressure, exerted on an object is based on the base area and weight of the object. This is the average amount of pressure exerted by the object over the entire base surface. This measurement can be relevant for judging whether a platform can support an object. An object with a large base area exerts less pressure than an object the same weight with a smaller base area.
