Conservation of momentum

[shiva2999]

According to the logic of the WTC1&2 collapses, this guy should just plow through these cardboard boxes with no appreciable resistance and splatter his dumb ass into a million pieces.

And yet he doesn't.

Why is that?

Maybe because the boxes weren't cut where no one could see?

Gee, no bites from the "heavy thing falling causes total destruction, concrete pulverization, molten metal and earthquakes" crowd?

Where's Frank Greening when you need him?

[Green Lantern]

Damn. I thought this thread was about how to lose a majority in the House despite your opponents revealing their stupidity by installing Pelosi in leadership.

That would be a good thread.

[Gilly]

that was one ballsy jump thats for dang sure...

as for momentum stuff, i bet 20 floors of wtc weight would flatten whatever was below it pretty quick..

Why would 20 floors ot wtc weight flatten 80 floors of uncompromised structure?

[Ru]

Cause this is 9/11 Land where the laws of physics no longer apply.

that the million dollar question and the difference between us, its alot of weight and momentum moving in a way the building wasnt designed for, could it go straight down? maybe, its how it looked to me on tv.

should it have fallen off the side? thats what the evidence seems to tell you all.

we have a difference of opinion here, and since we will not change each others mind i ll just leave it as that.

That's fine as long as you understand the point I've tried to make with this thread and the Criss Angel thread.

Sometimes what you see, what you think you see and what's really going on are three distinct things.

Sometimes our senses aren't enough.

Unless the 80 floors below it were NOT of the weight and strength of the 20 floors above it.

LOL

No. LMAO.

No. ROFLMFAO.

No. :rofl:

Too easy.

[Green Lantern]

If you threw a box at that pile of boxes, what do you think would happen?

[sukie]

what happens when a tall house of cards is constructed and you drop 30 additional floors worth of cards onto it from one card length in height? Static load vs dynamic load.

q is number of inelastic collision, k is the index for the summation.

Because each of the remaning 80 are not designed to hold the weight of the 20 that
fell on them..........79,78,77,76,

Gee, how were they supporting them for the last 40 years?

Magic?

All the cards in the WTC building were Kraz-ee glued together.

Try again.

Static load bearing

[Green Lantern]

Static load bearing

How much extra force is accumulated from an 8 ft. drop?

[shiva2999]

Static load bearing

Go jump on a cardboard box.

[GOPchick]

My first question here is how in the heck did this guy live?

Holy shit! That is one crazy guy to do that!

Amazing, isn't it?

But the fact is stuntmen have been doing high falls into cardboard boxes since the invention of the motion picture camera.

very amazing! But why cardboard boxes? Why do people live when falling into boxes? This is very intersting shit!

Your feet are static load bearing. So what?

[shiva2999]

Indeed. I am trying to get a certain section of the board to address it but, alas, they don't seem to want to.

well I want to so screw them.

how far up do you think he was? How many feet?

How many rows of boxes were there - I couldn't tell 100% It looked like 5 or 6?

[shiva2999]

He fell about 150' and looked like he weighed about 150 lbs.

That's a shitload of kinetic energy.

To think it could be slowed and then stopped by a few dozen empty cardboard boxes is pretty ****ing amazing, isn't it?

I think he weighed more not sure if that matters. I watched that video about 3 times in a row.

It is very amazing. Some of the people who feel out of the towers feel about that many feet and to think all they had to do is put some empty boxes down there we would have had a lot more suvivors.

[35Pete]

According to the 9/11 crowd Shiva, structural failure of the boxes caused that man to crash through those boxes without losing any kinetic energy.

He's dead. It's just a hoax.

The video DID stop before I saw him get up and walk away.

[GOPchick]

yeah but you could still here him making noise

[shiva2999]

The highest one I ever supervised was 80' feet into 10' of boxes.

Why don't people get this?

Today I picked up a bullet and tossed it at my head. Therefore, how can one shot from a gun hurt me?

[Mouldsie]

lol that line needs to be in a will ferrel movie

[sukie]

Your feet are static load bearing. So what?

So if I fell 12 feet the load on my feet would be more than 197 lbs. Ouch.

[shiva2999]

Try a sack of hammers instead.

I'm sure a guy like you has one lying around somewhere.

Problem is that the top of the building started at ZERO velocity. Why don't you get that?

The intiation of collapse started (110-80)/80 = 73% above the rest of the building. Are you trying to suggest that the top 27% caused the bottom 73% to collapse that fast?

I'd like to see those numbers. I really would.

Yeah it's heavy. So what?

[sukie]

Pete wouldn't the above stories accelerate downward the 12 feet at about 18-19 mph?

[shiva2999]

How fast was our jumper falling sukie?

[GOPchick]

I want to know what is the significance to the card board boxes? Why do thye fall into them?

[shiva2999]

I want to know what is the significance to the card board boxes? Why do thye fall into them?

Because cardboard boxes, as flimsy as they are, dissipate the falling object's kinetic energy.

Just like the bottom 80 floors of the WTC would dissipate the kinetic energy of the falling 20 floors.

[sukie]

Except Cardboard Boxed are homogeneous in nature on all six sides. Cut out four of the six sides for windows and leave top and bottom intact. Then try experiment.

The...stupidity...never...stops...

[sukie]

Is a building built with homogeneity on all six sides?

[shiva2999]

Sigh.

[sukie]

Oh Petey...

[35Pete]

mph is speed in ft/sec. Acceleration is in ft/s^2.

The top of the building started at 0 ft/sec.

[35Pete]

Oh Petey...

You're physics knowledge is pathetic. The answer is no.,

[sukie]

Why load on my feet from 12 feet of drop should be the same?

[sukie]

mph is speed in ft/sec. Acceleration is in ft/s^2.

The top of the building started at 0 ft/sec.

I understand zero but what is the speed at 12 feet?

[35Pete]

I understand zero but what is the speed at 12 feet?

I already calculated it. Prove to me that you know what you are talking about and tell me please.

[sukie]

Is the speed around 19 mph? Give or take for mass x?

[35Pete]

Is the speed around 19 mph? Give or take for mass x?

The speed at free fall is independent of mass. So you don't know what you are talking about?

Mass only comes into play when momentum is reduced. That reduces KE and hence v resulting in decreased acceleration.

LOL!

So, what should the speed be?

[35Pete]

I didn't think that I'd get an answer. So here. Educate yourself.

Actually you are right, but only for free fall. If the columsn buckled as you claim that would SLOW IT DOWN CONSIDERABLY But the building top started at 0 mph. It dropped 12 feet in AT LEAST .864 seconds.

http://i6.photobucket.com/albums/y241/35Pete/feet_sec.jpg

For free fall only, which kinda contradicts your assertion that they didn't fall too fast. Know what I mean Vern?

[sukie]

So the buckling slows it down... what? About 18ish mph?

Seriously, get some medicine.

"Are you trying to suggest." No, I watched it. Are you drunk?

Seriously Go screw yourself.

[Green Lantern]

I'm drunk.

I'm ordering Bing Crosby albums online and looking for pictures of Rita Moreno naked.

Yes you are drunk.

[Mr. Politenessman]

Seriously Go screw yourself.

I am afraid I might scratch my dick on the tinfoil.

[Green Lantern]

Yes you are drunk.

I'm so drunk I'm using contractions. That is a big no-no in academia. Screw those tightasses though.

[jimmifli]

****'em.

Did you know after LBJ left office he grew a ponytail and became a hippie? More useless shit I know.

He was terrified of dying alone and they found him on his bed after his death clutching a phone. Poor bastard.
