Some back of the envelope calculations: An Olympic swimming pool is 50m long so that should also be the height of the tower. Gravity is 9.81ms-2 . Assume the top guy falls only due to gravity with no wind resistance or effects from the pivoting tower etc. Applying Newton's Laws of motion the top guy will take at least 3.19s to fall. The current world record is about 22s, so this strategy seems feasible.

However, top guy is going to hit the water at something like 27ms-1 in a straight on belly flop and it's going to fucking hurt.

Obviously there are other issues involved, so it's unlikely to work in the real world.

What about the weight for the bottom guy?

Shhh. I'm doing science.

Also, while you are tabulating science, I am confused by your username MRH the pie... What awful/amazing thing are you suggesting that we do to the pie?

Actually they're my initials... It's nice to meet another pie.

I've finished tabulating science:

Well it is clear from the tabbed science that you have presenting that the guy on the bottom is going to have a bad time.

I read it as Mr. H, the pie. still works [if you're a dude]!

So I created a dynamics equation that looked at rotation of a bar about the end of it. Also took into account wind resistance. This results in a non linear differential equation so I simulated it using ode45 in Matlab and came up with the top guy going about 36 m/s right before he hits the water, that's like 80 mph, I do not think he would live ha. Too bad someone beat me to the punch, damn you backs of envelopes!

My parameters: height of tower = 50 m, mass of person = 75 kg, height of person = 1.66m, width of human body = 0.4 m, depth of human = 0.15 m, density of air = 1.2 kg/m3, Cd = 0.4, moment of inertia of tower I = (m*L3) /3 and of course g = 9.81 m/s2.

We must also factor in that he is falling in an arc and must fall a longer distance. He is essentially falling (if this is a right triangle with 50m legs) a length of ~70.7 meters. His acceleration due to gravity would be different (in a way I admittedly either cannot calculate or don't feel like remembering how to calculate) to a degree that would completely change his velocity. Finally hitting water at that height and in that position would likely cause enough internal injury to kill you.

I was really hoping they would fall backwards, I'm a bad person.

Or reach the ceiling and then start climbing onto (into?) it starting with the guy on the bottom.

Not a science guy, but wouldn't the top guy hit the water last? It coulda' gone something like this.

[–][deleted] 1 point2 points ago

sorry, this has been archived and can no longer be voted on

They would all hit the water at the same time.

Think about it like a spoke on a bicycle wheel: as the spoke goes around in a circle, all points of a single spoke complete one revolution in the same time. However, the point on the spoke farthest from the center actually travels faster because it has to move at a greater distance in the same amount of time.

Due to the force of gravity being that of acceleration, the velocity of the man on the top is actually much greater than the velocity of the man on the bottom when they make contact with the water.

At first I thought you wrote fist fucking. Then I read again, and you did. So then I followed my heart, and fapped to the filthiest fisting I could find. I am dirty.

This is obviously fake; there's no way the guy on the bottom could support that weight.

I always appreciate when someone uses a semicolon correctly; I, for one, always seem to mess it up.

Some Asians pull white off pretty well.

But how 'white' are we talking?

Gotta be fake. Guy on the top of the tower would die from hitting the water that fast stretched out.

[–]polkapolkapolka 15 points16 points ago

Not before the bottom guy's shins collapsed onto themselves.

Someone else pointed out that an olympic pool is 50m. Over-estimating by a lot (to low-ball the actual weight), let's say 1 asian = 2m. (it's more like 1.7m on average)

So that's 24 people standing on top of one guy. According to a height-weight chart, and using the 1.7m height and "small frame" (just to under-estimate what the true weight would be, better to be under than to be over), average weight should be around 63kg.

63kg * 24 people = 1512kg (3333.3lbs)

Or, 1.2 Honda Civics.

[–]box951 36 points37 points ago

Is that the new standard now, convert all units of weight into honda civics?

[–]polkapolkapolka 18 points19 points ago

Or: 50.5 million grains of rice (assuming 1 grain = 30milligrams).

At 0.0367142857 calories per grain, with 257 calories per 8oz serving, and assuming approximately 7000 grains per serving, that much rice would feed all 25 tower members for 38 days.

That much rice stores 7.75 million joules of energy - enough to drive the Civic 2.3 miles highway, 1.7 miles city.

[–]box951 13 points14 points ago

sorry, this has been archived and can no longer be voted on

So, what we've learned today:

1512 kg equals roughly 2 miles

only for Japanese. If these were Americans, you would convert to Corvettes. Italian: Ferarris... you get the drift.

[–]box951 0 points1 point ago

Ok, this makes much more sense. Thanks for the clarification

[–]krispyKRAKEN 0 points1 point ago

Yes because Hondas are equivalent to Ferarris and Corvettes... nice try Honda salesman.

1.7m per Asian? HAHAHA

[–]JimmyJamesincorp -1 points0 points ago

sorry, this has been archived and can no longer be voted on

It's way less than 1.7m, because their limbs connect with each other. This makes the tower grow about a torso + head size per asian.
