Do we agree the towers were designed to withstand jetliner crash?

[JayUtah]

I cannot begin to count the number of times our Mac Pros have hung up or I have had to shut down programs and relaunch them.

Exactly; in the grand scheme of things a personal computer is appealing commercially only if it sports lots of bells and whistles and doesn't cost a lot, and has only minimal consequences of failure.

Contrast that with a launch-vehicle control computer. It needs no bells or whistles (or even a keyboard, mouse, or monitory), and if it fails there is loss of considerable property, or (in the case of human-rated launch vehicles) loss of life. Hence we tolerate very little failure in those designs and charge you obscene amounts of money to achieve that reliability.

Most non-engineers don't understand what engineering really is. It isn't tinkering with aluminum or resistors or computer programs. Instead it's finding the "good enough" sweet spot so that things can actually be built, function, and aid humanity while failing only in tolerable ways.

Engineers can envision far more failure than they can avoid, or than can be practically avoided. Each additional magnitude of reliability generally comes at a magnitude increase in cost, and generally also has qualitative effects on the common case. This makes it prohibitively difficult or expensive to build, and actually ends up reducing overall reliability because of the burdened common case.

In the case of WTC and a unified model of structural performance, impact analysis, fire propagation analysis, combustible modeling -- it just didn't exist in the 1960s. It doesn't exist now, although we're getting there. You did the best with the tools you had available, and you accepted that there would be many, many things outside your ability to study and quantify, outside your ability to correct and control for, outside your ability to afford, and outside your imagination.

(like two 3/8 inch long, 1/8inch diameter, bolts into a plastic frame will hold a 20 oz battery in place!)

Sounds like a problem gaffer tape was meant to solve.

ok, I suppose if you have billions of years to toss around a more efficient distribution system isn't required.

Hey, maybe God just likes to Blow Things Up Real Good.

 

[LSSBB]

Any location with an HR-2 office or higher will do.
yes a TS-SCI clearance will get you into up to level 3 stations (good enough for paid internet shill positions). The outer offices at the Pentagon and Denver are level 1 BTW. Stay back from the blue line on the floor though and do not approach any doors except the exit unless specifically cleared. You have to 'read in' for level 4 after which access will be granted to higher levels on a merit and qualifications basis.

I'll make sure I have my Green Pen and Robin's Egg Blue paper also...

Any engineering risk that could lead to structural failure would be anathema for the engineers.

Obviously not an Engineer. Huh? Even Engineers can't stop everything!

 

[Sunstealer]

MM,

Seeing as you are an engineering guru could you please describe/define, using your own words (so we can see you understand them), the following terms;

1. Confidence Limit e.g. 95% confidence limit.

2. Safety factor.

Thanks

They had all the data for the projectile, a Boeing 707.

Are you one of those fake truthers who are paid to spread the myth that planes hit the WTC?

Or are you just gullible enough to believe the OFFICIAL STORY of light aluminum planes (160 tons) magically defying Newtonian physics by penetrating a solid steel-framed structure of 250 THOUSAND tons each, through the path of greatest resistance, for the first time in history?!?



Go learn physics, you disinfo agent.

Damn, you found him out, SfT! MM is in reality Harry in IT up here in the gleaming NWO Towers. I think you'd be surprised to know his office is only one floor below yours. I'm sure you've seen him--he's the guy with the pocket protector who comes up and fixes the computers and printers here. The boy set me up with a SWEET microphone and speaker setup for my Skype calls to Illuminati HQ. Treat him right, he'll take care of you.

Anyhoo, I'll tell you what; the next time Harry and I go out for a couple beers, I'll let you know. He's a RIOT.

Looks like MM and NB have "left the building" along with Elvis...

Are you saying that Newtonian physics prove that a light baseball cannot penetrate a car windshield because the car weighs 2 tons?

Do you understand what localized failure is? Obviously not.

Also, your claim about the towers being "solid steel" is laughable. You do realize that the perimeter columns at that level were made of 1/4 plate and were NOT solid right?



Can you explain how a B-25 bomber penetrated the out exterior of the Empire State building back in 1945? Why didn't your supposed understanding of Newtonian physics apply that day?

Really?

So I'm an engineer designing a building in a downtown city. This building is going to be next to a curved highway bridge.

Are you telling me that I have to do calculations to make sure it can survive a fully loaded tanker truck carrying gasoline, the driver losing control, smashing through the concrete barrier of the bridge, smashing into the building, and causing fires? Do I have to take into account that the fire suppression system is possibly knocked out?

What if that tanker was carrying some other flammable liquid? What if it was very cold out and a water main supplying the fire system ruptured rendering it useless? What if two trucks of the same description, following each other, both lost control and smashed through the concrete barrier and into the building, but at slightly different locations?

Is it possible a plane could lose control and smash into the building because the city is near an airport? Do I calculate for that also?

You have no clue whatsoever.

You forgot the 200 mph hurricane and the 8.3 earthquake happening at the same time.

Apparently MM thinks that engineers use the Calvin and Hobbes worst-case scenario as a design criterion: the farmer about to light his stove, unaware of the leaking gas line in his house which is built on a major tectonic fault line, next to the tracks from which a freight train has just derailed, as the jumbo jet falls from the sky above...

Expoxy. The battery plate will now no longer be removable, but at least if they tilt the camera upwards the camera still has power.

OMG, I left that part out didn't I.
Good thing you caught it.

Don't forget the termites, who, alarmed by hurricane and earthquake, relocate to the basement and start eating the concrete, just as a tsunami rushes in...

 

[jaydeehess]

Perhaps an analogy would help MM

Try to imagine the difference in video editing that was possible in 1964 versus what one can do with a modern Avid or Final Cut suite, both in terms of cuts, fades, overlays, etc, and in man hours required to accomplish the task.
