View Full Version : Engineers ruin Christmas (HALARIOUS!!)

Bein an engineer i found this halarious... hopefully u all get most of it and can laugh!




There are approximately two billion children (persons under 18) in the
world. However, since Santa does not usually visit children of Muslim,
Hindu, Jewish or Buddhist religions, this reduces the workload for
Christmas night to 15% of the total, or 378 million (according to the
population reference bureau). At an average (census) rate of 3.5
children per household, that comes to 108 million homes presuming there
is at least one good child in each.

Santa has about 31 hours of Christmas to work with, thanks to the
different time zones and the rotation of the earth, assuming east to
west (which seems logical). This works out to 967.7 visits per second.
This is to say that for each Christian household with a good child,
Santa has around 1/1000th of a second to park the sleigh, hop out, jump
down the chimney, fill the stocking, distribute the remaining presents
under the tree, eat whatever snacks have been left for him, get back up
the chimney, jump into the sleigh and get onto the next house.

Assuming that each of these 108 million stops is evenly distributed
around the earth (which, of course, we know to be false, but will accept
for the purposes of our calculations), we are now talking about 0.78
miles per household -a total trip of 75.5 million miles, not counting
bathroom stops or breaks. This means Santa's sleigh is moving at 650
miles per second--3,000 times the speed of sound. For purposes of
comparison, the fastest man made vehicle, the Ulysses space probe, and
moves at a poky 27.4 miles per second, and a conventional reindeer can
run (at best) 15 miles per hour.

The payload of the sleigh adds another interesting element. Assuming
that each child gets nothing more than a medium sized LEGO set (two
pounds), the sleigh is carrying over 500 thousand tons, not counting
Santa himself. On land, a conventional reindeer can pull no more than
300 pounds. Even granting that the "flying" reindeer can pull 10 times
the normal amount, the job can't be done with eight or even nine of
them---Santa would need 360,000 of them. This increases the payload, not
counting the weight of the sleigh, another 54,000 tons, or roughly seven
times the weight of the Queen Elizabeth (the ship, not the monarch).
600,000 tons traveling at 650 miles per second creates enormous air
resistance - this would heat up the reindeer in the same fashion as a
spacecraft reentering the earth's atmosphere.

The lead pair of reindeer would adsorb 14.3 quintillion joules of energy
per second each. In short, they would burst into flames almost
instantaneously, exposing the reindeer behind them and creating
deafening sonic booms in their wake. The entire reindeer team would be
vaporized within 4.26 thousandths of a second, or right about the time
Santa reached the fifth house on his trip. Not that it matters, however,
since Santa, as a result of accelerating from a dead stop to 650 m.p.s.
in .001 seconds, would be subjected to acceleration forces of 17,000
g's. A 250 pound Santa (which seems ludicrously slim) would be pinned to
the back of the sleigh by 4,315,015 pounds of force, instantly crushing
his bones and organs and reducing him to a quivering blob of pink goo.

Therefore, if Santa did exist, he's dead now.

Thats too funny. I cant believe someone actually sat down and calculated all that out!

That is funny, they should have added something in extra that would have put it over the top. When they talk about how much the sleigh would weigh with all the presents and reindeer and stuff, like 7 times that of the queen elizabeth, they should have stated how if that landed on your house it would demolish it and kill everyone inside. hahaha

haha i'll sit down tonight with a few engineers and see what we can come up with!

Maybe that's the trick. Maybe, by magic, those reindeer absorb that 14.3 quintillion joules of energy each second. I wonder if that's enough to accelerate 600,000 tons to 650 miles per second in 0.001 seconds?

Wilkin ... you're the genius on here ... you do the math and let us know if it's possible . :p

Wilkin IS the smartest here. He's already figured it out.

Santas not about calculations, science and facts.
Santa's about magic and happiness in children hearts.

Well i guess santa got his cheat codes from www.cheatcc.com


yeah he's pretty good....

is that what your trying to say?haha

wilkin250r
12-07-2005, 04:12 PM
Sadly, I calculate that the reindeer expend 333 quintillion joules of energy just in acceleration, a far cry from 14.8 quintillion they are absorbing every second.

Tommy, can you double-check my work? :devil:

ok heres what i've found... i did this fast but heres some of it... i'll type it out so show everyone how i did it...

santa is traveling at 650 mi/s which is converted to 3,436,550 ft/s or 1,047,460 m/s...

to get his acceleration we use veloctiy = accleration (time)... time is .001 and velocity is 1,047,460 m/s so he would have to accelerate at 1047460440 m/s squared...

if his sleigh was to weight 600,000 tons which is 544,320,000kg

then using the simple equation of Force = Mass (accel) we get that the force acting on santa is 5.70153 x 10^17 kg/(m/s squared) or Newtons...

so the distance that santa travels is Distance = 1/2 (acceleration)(time)^2 so he travels 523.73 meters in .001 seconds...

so then we can use Work = Force(distance) so he does 2.98 x 10^20 joules of work or 298 x 10^18...

so i got 298 quintillian joules of work to accelerate to 650mi/sec with a 600,00 ton sleigh in .001 seconds...


it could be rounding error on my part... i didn't go very exact bc i was in a hurry!

little do you guys know that santa freezes time with his "magic" then has the elfs go ape shiet on dropping everything off

Well, it's a good thing I had you double-check my work. Turns out, we BOTH had mistakes.

First off, there are 5280 feet in every mile, so 650 miles/sec comes to 3,432,000 ft/s, which comes out to 1,046,074 m/s.

Which means acceleration comes to 1,046,074,000 m/s^2.

However, I had a slightly larger mistake. For weight, I came up with 609,628,100 kg, but you are correct with 544,320,000kg.


I got schooled by the young whippersnapper... :(

what i did is not very hard... infact someone in middle school could carry out the math its just mulitplication and divide with a few basic physics equations!


the only thing i dunno about is the US standard to metric conversion... i never have to deal with that type of stuff... everything is given to us in metric!


my one teacher here was the part of the nasa project that crashed because she did the conversions wrong... the one time she gave us standard to american on a test and we said WHAT? shes like you can do it... one kid in the back said well we know you can't! WRONG THING TO SAY!

ouch i had there are 5287 feet in a mile! opps my bad... that right there would be my problem:( i knew i'd mess up the conversions somewhere

That's fine. You have a 0.1% error.

I have a 12% error. I converted using a long ton (2240 lbs) instead of the standard short ton (2000 lbs).

Unless Santa is British. They use the long ton over there, so I might be right after all.

I personally wish america would adopt the metric system... it so much easier to use and would make our lives so much easier! haha

right now i'm in physics thats dealing with things such as gauss law, amperes law, change in flux, etc and man does it suck!

No way, that was the best part of engineering physics. Of course, I was always on the path to electrical engineering, so it was thermodynamics that sucked for me. Boyle's law, ect ect.

Have you met our good friend Maxwell, and his wonderful equations yet? Gaussian spheres, gradients, blah blah blah...

thats exactly what i'm doing!!! i just got done with maxwell and the equations for speed of light and his rewriting of amperes law...


i don't like electricity, currents, compacitor resister inductor circuits, and things like that very much... for some reason i always get directions wrong or can't figure out voltages or currents...

i got 3 MAJOR finals tomorrow and had one today... i got a physics 212 (all the stuff we were talking about), Math141 which is like integrals, series, and polar coordinates... then a statics physics one which is like trusses, moments, etc...


its a miracle i can even think enouf that i can make myself breath my head hurts so bad right now! haha

nice job guys.... I didnt have time last night.

I thought dynamics was easier than Statics, but thats just me...

Next term for me:

Heat transfer
Econ 480
Organic Chem
Fluid dynamics
Comm 2


last term:

Dynamics
