The Heiwa Challenge

[Jonnyclueless]

The Heiwa Challenge is independent of scale! Small or big!

And independent of engineering or reality.

f only they had built the WTC out of large pizza boxes. Say, why don't you recommend building buildings out of large pizza boxes and see how much work you get.

Pizza boxes are exceptionally stout, but unfortunately, they're not economical for tall buildings. Building designers experimented with pizza box construction during the late 20th century. They had overcome the dripping mozzarella problem and the greasy pepperoni headbanger problem and then some jerk came along and developed structural steel and all that work on the super-duper awesome structural pizza box when out the window.

The Heiwa Challenge is about a structure A that is one-way crushed down by a part C of same structure, where C=1/10A volume/mass wise and dropped on A using gravity. Only structure inside A and C shall be same. As already pointed out many times structures like pizza boxes, sponges, lemons, mice, elephants, &c, do not perform as requested. You'll have to find another structure using your engineering skills and brains (if any). Go for it! I'll take vaccation until end May.

That doesn't address the issue of scale. Think about it this way: If I throw a bullet at a watermelon, what happens? Now what happens when I fire a bullet at the same melon? Remember, the only difference in my example is scale.

Is scale important in the way physical reality operates, "heiwa," yes or no?

You say goodbye, and I say hello

You mean like a 110 story building identical to the WTC towers?

I'm sorry, but I mistakenly thought non-toofers were intelligent enough to understand the Challenge. Mackey understands it, and Mackey knows it can't be done. As for the others? No chance.

You're right... Heiwa demonstrates his knowledge with pizza boxes after all -- the ultimate and most delicious model of a building evar. How real professionals could ever doubt the integrity of lemons, pizza, and coconuts is absolutely beyooond baffling.

Says a guy who understands it less than anyone here to the point that he takes it seriously and without laughing.

At first, I think that living in a Pizza Box Tower would be a novel idea. I love pizza; it's probably my favorite food, and I find the aroma of the toasted crust, roasted tomatos, cheese, fennel, oregano and the other toppings I like to be simply intoxicating. However, I think it would lose it's appeal fairly quickly when you either a) eventually tired of the smell, losing any desire to eat pizza for the rest of your life, or b) were hit with your first stout breeze.

 

[Minadin]

Please note: I don't think I would put lemons and coconuts on the same pie.

Does gravity exist in Heiwa's world?

 

[Furcifer]

Does gravity exist in Heiwa's world?

Only as a force that can be easily overcome with enough displacement.

It seems there are few contenders in the Heiwa Challenge! To assist I have made a new show at http://heiwaco.tripod.com/funnym.htm !

On 911 two towers prove Heiwa is a fraud; you on the other hand lack the knowledge to understand the same proved by your post. In the 7 years, 7 months and 20 days after 911 you could have earned a degree, two degrees in Engineering by you have decided to spew delusions on 911 and remain in ignorance with 911Truth.

Heiwa make crazy ideas about 911 with drops of 2 miles that would be arrested by the structure and you jumped on his sinking ship of nut case ideas on 911. And you can't swim.

From http://heiwaco.tripod.com/funnym.htm:

Right we see a Funny m structure/tower on ground with n = 22 Funny m assemblies.

The total mass of this structure is n m (or 22 m)

The potential energy of each m is its distance above ground times g, where g is gravity acceleration.

The total Potential Energy, PE, stored in the structure is the sum of the PE of each m or n * m * n * h * g /2 or

PE = (n²mhg)/2

Okay so far...

The springs... can compress 0.003h elastically and 0.005h plastically before they break (in this example) as already explained.

In the intact tower right all springs compression is d = 0.001h, i.e. hardly visible. Thus n m will compress the tower n d or 0.001nh.

The spring constants C for all springs are thus known. Each spring can in fact carry 3 times more m than it is certified for, before it starts to deform plastically.

Still okay so far...

Thus, the total elastic and plastic Strain Energy, SE, stored in the intact tower structure is known. It is actually the PE mentioned above!

Wrong.

It is in fact .001 times that amount.

That's the factor by which the the height of each mass is reduced, due to the compression of the springs.

PE at all times equals (n²mhg)/2, where h is the actual height per floor taking any compression of the columns into account. If we call the height per floor with no mass loading and therefore no spring compression h₀, and we know each spring compresses by .001*h₀, then

PE = (n²m(h₀*.999)g)/2
SE = (n²m(h₀*.001)g)/2

Following through with your analysis after correcting this error,

SE_max = 3(n²m(h₀*.001)g)/2

and the remaining 99.7% of the PE is ample for continuing to compress the springs through their plastic limit and then to failure.

Thus, the results of Experiments 1, 2, and 3 are: that sucker's coming down.

Respectfully,
Myriad

OK, so the Funny m Tower SE (or strenght!) is just 1/1000th of what I suggest but it still manages to keep the tower standing. Quite good!
I hope you agree that you can still load the Funny m Tower , i.e. increase m to 3 m in every assembly n and that the Tower still stands (assuming the ground will resist it)? The foundation/ground is assumed rigid in this little show, so it will resist!

And I hope you also agree that if you put 6 m up on the top Funny m assembly, it is only the springs below that element that breaks?

And what's the difference of adding potential energy up top or dropping the top part = apply kinetic energy to achieve the same result?

And, finally, I hope you agree that the top part C of the Funny m Tower is not rigid (as assumed by Bazant in his peer reviewed papers) as it contains the weakest springs in the whole Tower?

BTW - how are you getting along with your 10 meters tall crush-down model?

Beware that it doesn't collapse on you during construction!

Did you just admit your calculations were wrong by a factor of 1,000 ?

 

[Heiwa]

Did you just admit your calculations were wrong by a factor of 1,000 ?

I am just assisting Myriad as a (the only?) Heiwa Challenge contender and to ensure that Myriad will not kill himself when assembling his structure. It seems we have have different opinions what SE is and how to calculate it and what it means! My suggestion is ... always ... calculate 10 times before building and check each calculation 10 times. Safety first! And then check 10 times again! Maybe Myriad doesn't know what SE really is and is 1000 times wrong?

 

[WilliamSeger]

Do not, under any circumstances, board any ship designed by Anders Björkman. (Fortunately, it seems that experiment has never been attempted.)

Heiwa, I'm still waiting for your explanation for how two floors of the Skyline Towers building managed to crash through 22+ floors, and why you eliminated that example from your phony "challenge."
