Hey /sci/, if you build a tower of hamburgers from Earth to Mars

it depends. is it in europe. probably several gigatons.

in america? quarterpound with cheese.

Distance from Earth to Mars in millimeters:
225,000,000,000,000

Height of one average 300g burger in millimeters:
100

Weight of one average burger granted it is only bun and burger ~330g

Amount of burgers you could tower on top of eachother: 225,000,000,000,000/100 =
2,250,000,000,000 burgers

Weight of the sum of all burgers minus the one on earth: 2,250,000,000,000*330 - 1 =
742,499,999,999,999 grams.
Translate to weight:
742,499,999,999,999 / g = 742,499,999,999,999 / 9.81 =

75,688,073,390,000 Newtons is the weight they would all put on the first burger given that Mars doesn't affect the burgers near him such as for instance the last burger, etc. If Mars does come into the calculation the weight on the first burger on earth would be much less.

my bad, not 2250000000000*330 - 1 , it should be 2250000000000*330 - 330

>>7728973

you forgot that gravity would decrease the further the hamburgers were from earth, and the hamburgers in open space would likely not have any signficant contributing force

Like this?
A whopping 86000 Newton

You have to mention the weigh of the burgers on the burgers itself and the drecreasing of their heigh :/ pretty complex

>>7728989
>the hamburgers in open space would likely not have any signficant contributing force
this
i think you can disregard all hamburgers beyond Earths atmosphere, say beyond 100 km

>>7728989

>i think you can disregard all hamburgers beyond Earths atmosphere

Why?

>>7728993

Is treating it like a point mass valid? Wouldn't that mean increasing tower height would decrease force (mass increases linearly but 1/r^2 decreases quadratically)?

>>7729033
That is practically like the surface, gravity would not change much at that small height.

>>7729036
cos them burgers > 100 km would effectively be weightless, i.e. not pressing down on the lower ones

>>7729069
so make it 300km or 500km, whatever the agreed height is

>>7729036
At some point the amount of force they exert will be nil. I will say that anything beyond the halfway point will be in the negatives. So for the sake of figuring out force exerted you should ignore those as well.

>>7729057
You're probably right actually. I will redo it in a bit and just sum over all the burgers whose attraction to the earth is larger than the attraction to mars. That should probably do it.

They would be weightless as soon as it reaches space(no gravity)

>>7729081
That's not how gravity works, they will have weight all the way up

>>7729153
weight != mass

>>7729153
Up till space you mean

There is no gravity in space it's a vacuum
You have weight mixed up with mass too

>>7728338

The real question is, how do you hold a tower of hamburgers together from the Earth to Mars?

You literally can't build a tower of hamburgers that tall because the stress would be too big and the burgers would turn to mush. Even if they survive the stress they would still compress from their weight and with the changing gravity I don't fucking know OP.
You gotta give us some values, like the elasticity module for the specific burger that will be used etc and what part of the earth the tower will be on

>>7729194
There is as much gravity in vacuum, if you do not have a spaceship to hold you up you will fall to earth. Hamburgers are not on a spaceship and they will all fall down to earth, and that means weight.

>>7729206
Surround it by an indestructable tube for the sake of argument.

>>7729216
Have you ever tried building anything with hamburgers? They share the load evenly with a soft bun on each. They end up retaining their shape mostly, because each hamburger shares the load evenly and there's a lot of give, it's the same principle that allows corn flakes to be stored in a giant vat and the ones on the bottom aren't crushed.

Get a hamburger engineering degree before painting lies in such broad brushstrokes pls

He is right you morons, gravity has no distance limit.

That pretty much explains NASA in a nutshell.

>>7728338
>using burgers for going to Mars
Ameritard science

>>7729397
it decreases quadratically though

after a certain distance you can ignore the weight of the far away burgers

>>7729081
you are an idiot
atmosphere has nothing to do with gravitation

>>7729429
The people who are starving are starving because they are stupid, violent, unproductive assholes, not because NASA is pushing the limits of what the best and brightest of life on earth can achieve.

If we feed the evil in the world all we end up with is more evil and less good.

I don't want civilization to die, so yes I would rather build a hamburger space elevator.

>>7729250
You mean just measure the distance to Mars in hamburgers?

since no one in this thread understands gravity I will use
>>7728973
parameters to calculate with both Mars' gravity and Earth's altitude variant gravity based on this equation in the pic
where g0 is the standard gravitational acceleration, re is the planet's mean radius, h is the altitude of the burger, gh is the gravitational force applied by the burger at that height

The first calculation will be for burgers only feeling the force of the Earth's gravity

A burger at height h applies a force of m*(9.8)*((6137000/(6137000+h))^2)
To account for a stack of burgers, we will assume a burger stack with uniform density, and can then model the force of the stack as an integral of this equation from .1 m to 225000000000 m with respect to h with mass of a burger equal to .33 kg times 10 burgers per meter of burger stack
The integral is -m*(369095136200000/(h + 6137000))
evaluated at our height range and plugging in m we get -3.3*((369095136200000/(225000000000 + 6137000)) - (369095136200000/(.1 + 6137000))) =
198465163.51838 Newtons

If we include Mars and assume that the stack is touching Mars on the other end, we just repeat the method with the new equation for gravitational force which is the difference of the force of Earth's gravity and the force of Mars' gravity:
3.3*(9.8*(6137000/(h+6137000))^2 - 3.7*(3390000/(225000000000 - h + 3390000))^2)
height from Mars is represented as (225000000000 - h) meters
reevaluating the integral with this new gravitation gives us
157073886.63 Newtons

This second calculation might need revision because it assumes that the burgers are stuck to each other, so if Mars pulls a burger toward itself harder than the Earth pulling the burger downward, the calculation includes that upward force as pulling upward on the bottom burger so the true answer to this second part is probably much closer to the first calculation
