Its a statement with regard to the weight of a material as can be found generally in a level, floor, area, etc. Not pressure in this context. Just face, you're wrong.

Wow you never give up do you?

Again context doesn't matter PSF, PSI, etc., are measurements of pressure, period. PSF will never mean weight. The PS stands for pounds per square...

Pounds or pound force per square inch (psi, lb/in^2, pfsi or lbf/in^2) is a widely used British and American unit of measure for pressure. 1 psi equals 6,894.76 Pascals.

Safety factors are measured in pressure, not weight. For example, the FoS of a floor is calculated by taking the weight the floor is expected to hold over it's lifetime, and calculating the pressure the floor has to withhold in order to not collapse from the expected weight it is to hold.

Yes I'm replying to an old post, so shoot me, but this is typical of OSers here, they will stand by their claims no matter how many times you show then they're wrong. No evidence they're right, just empty claims.

Yeah, it does. Pounds of material per square foot for an average floor loading. Its a away to shorthand the loading. Think of a floor of a building. Think of the partition walls and the furniture and the appliance. They simply add up the gypborad, framing, ceiling material, furniture and appliance and prepare a schedule accordingly. So many pounds of gypboard and so many square feet of floor space, divide the two and you got 3 pounds of gypboard per square foot of floor. You are way out of your element here.

Yes Hooper, you are right.

But by definition the number of pounds on a given surface IS the pressure exerted on that body.

That is what pressure means, look it up. You cannot wriggle out of this one.

Think of it in terms of a gun: The amount of force exerted on the guy firing the bullet is exactly the same (nay more) than that exerted on the person getting hit by the bullet. The difference? Not the weight of the bullet, nor yet the speed of the bullet.

Verily Hooper, I say unto you, it is the very PRESSURE that the bullet exerts that makes the difference.

The difference between a black whole and a large star is the AREA that the mass occupies, not the mass itself.

Again, though, engineers are only really interested in the weight because the area is given. But the area is given Hooper. It is given because if you only had the weight you wouldn't know jack, the only thing that is of any interest is whether the supports can resist the PRESSURE it is subjected to by the weight, not how big the weight is.

Wow, I can't believe this argument is even necessary.

Let's remind you of what started this discussion shall we?

That is what you claimed. You are wrong. End of story. Everything you've said since is an attempt to wiggle out of your mistake. Why can't you just admit you're wrong?

I know how they do it, I explained that to you remember? They use the weight the floor is expected to hold over it's life span, but the calculations are done in PSF, pressure not weight, so they can construct the floor to withstand a certain pressure, because pressure is how you measure the force of a weight on an object. You fail to understand the concept. Weight puts pressure on the floor. Weight by itself means nothing because a different sized object, of the same weight, will create different pressure on the floor. More weight in a smaller area means more pressure on the floor. It's the reason you can lie down on a thin roof, or thin ice, and not go through, but try standing on it.

Pressure is the force on an object that is spread over a surface area [because it has weight Hooper, ANOK]. The equation for pressure is the force divided by the area where the force is applied.

Nope. The actual pressure or load varies. This is a shorthand way of conveying basic information about the weight and variety of material on a floor.

That is why it said PSF, because it a measurement of pressure, not weight.

It can be both, you must know the context. Its just that simple.

Oh for peets sake, no it can't. PSF is PSF dude. Pounds per square foot. 'Pounds per' is pressure, pound-force per square inch, PSI, or pound-force per square foot, PSF. It can not mean anything else. Weight is measured in pounds, not pounds per square feet, LBS not PSF. Context has nothing to do with it, it means the same thing in every single context..

Are you really this dense? Or do you feel the need to always have the last word, whether you're right or not?

Pounds or Pounds Force per Square Foot is an British (Imperial) and American pressure unit which is directly related to the psi pressure unit by a factor of 144 (1 sq ft = 12 in x 12 in = 144 sq in). 1 Pound per Square Foot equals 47.8803 Pascals.

The psf pressure unit is mostly for lower pressure applications such as specifying building structures to withstand a certain wind force or rating a building floor for maximum weight load.

I am amazed you are still trying to argue this hooper, just shows what extent you OS supporters will go to in order to continue with the OS fantasy. You are being intellectually dishonest hooper, and would argue the sky is green if the OS said it was.

It can mean pressure, like with steam or air. And it can be a simple description of the weight of various categories of materials in a location simplified in terms of square area. Depends on context.
