Accel Borrowing Earth's Rotational Power Calc

[Makina_Yuki]

Is there any calculation about accel vector control via borrowing earth's energy?
Theoretically to slow down earth rotation, you need control earth mantle because earth crust will move via mantle convection. Earth crust thickness up 5 Km to 50 Km and earth mantle average thickness 2885 Km. For reference, Indian Ocean earthquake and tsunami 2004 shortened the length of a day by 2.68 microseconds and total work done MW (and thus energy) by Indian ocean earthquake was 4.0×10^22 joules (source:https://en.wikipedia.org/wiki/2004_Indian_Ocean_earthquake_and_tsunami).

My calculation:
#Accel compared to Indian ocean earthquake
Accel slow down earth rotation by about 5 minutes (300000000 microsecond)
>comparison= 300000000/2.68= 111940298.507463
* which means 111940298.507463 times Indian ocean earthquake (2.68 microsecond).

1. Total energy= 111940298.507463 x (4.0×10^22 joules)= 4.5x10^30 joule

Is that mean accel is low-5B? Please correct my calculation if wrong.

An earthquake moves some of Earth's mass towards its center, And due to the conservation of angular momentum since the moment of inertia is getting smaller the rotational energy is getting bigger, thus making the day slightly shorter.The rotation of the planet has sped up while from what i understand Accel has slowed down the rotation.

After borrowing the energy the length of a day was 24 hours and 5 min?

I did it as part of this calc (and it was also done in the OBD somewhere).

Note that the calc itself isn't legit, only the energy part. so its about 10^27 J. Continent level

as listed.

^Ok it seems more acurate than my calc. But in geophysics, sub surface cannot be determinated by math. For example, basically earth is not homogeneous so we need standart asumption that earth is homogeneous and then using K (if in geoelectric method, K is geometry factor) as factor to determinate subsurface condition. Maybe we need this asumption in this calculation, also maybe your link should be added on accel page.

Hey I recalculate Indian ocean erathquake with DontTalk formula:

1. 2,68 microsecond=0,00000268 second

>T1=86400s ; T2=86400,00000268

>E=((1/2)*(2/5)*(5.9722*10^24kg)*(6371000.785m)^2*(2*¤Ç/86400,00000268s)^2)-((1/2)*(2/5)*(5.9722*10^24kg)*(6371000.785m)^2*(2*¤Ç/86400s)^2)=15889895754014100000

with that calculation, total work done by indian ocean earthquake is 1,59x10^19 joules. From wikipedia, total work done by Indian ocean earthquake is 4.0×10^22 joules. Maybe other factor can be added.

Earthquakes involve other things such as friction etc so it's logical that you wouldn't find the same value.

And thank you for completelly ignoring my comment.

 

[Makina_Yuki]

Im sorry if I make you upset, I really doesnt have intention to do it, but you not mention that other factor is ignored.

So you mean that mechanism is accel could filter other factor such as sub surface pressure etc and discard it, then he draw out earth rotational power without other energy that can be included to reach earth mantle. Well, If its just pure earth rotational power without other factor, DontTalk calc is reasonable.

Ok thanks for your explanation.

Meh, a certain friend of mine brought it up again today and it took quite a bit of serious consideration. Sorry if the thread's revival disturbs anybody but I guess that should not be a problem.

I got about 1.3*10^27J.

However, that is only under the condition where the angular velocity of earth was slowed over the period of 'a whole day', which results in a total difference of 5 minutes in the end and the conservation of energy was perfect during the process of Accelerator draining energy from it.

I meant, since it was written in the LN as 'In that instant, earth's rotation slowed by about 5 minutes for September 30', the following days should not be affected by this, as energy returned to the Earth after the collision, and he of course could not stop the whole planet, that would just erase the humanity (thanks to inertia), so that line did not mean he stopped the whole planet for 5 minutes (wait, is it possible for the Earth to orbit the Sun while not doing any self-rotation?)

If so then he reduced the angular velocity of the planet, so that it caused a difference of 5 minutes (hell, this is damn confusing, I meant, 'In that instant, earth's rotation slowed by about 5 min for Sept 30', it should mean that day was actually slowed by 5 min, but if the angular velocity was reduced then it shouldn't even be 'in that instant', and after the collision, energy/momentum returned to the Earth so the angular velocity would be accelerated again to where it had been.)

What did it even mean to be 'slowed by about 5 minutes' 'in that instant'? And even 10^27J is not reasonable at all!! With that much kinetic energy (resulted in frightening speed), even the concrete wall would just be destroyed in a blink of an eye when it collided with the other buildings, and that physics might not even work properly (high energy, high velocity), or he might just spent energy to fortify the wall (wow, do we have any calculation for this? I doubt this allows conservation of energy to work properly.)

I think we will not even get close to an actual result without knowing what it truly meant to be '5 minutes'.

Yeah, that is the main problem, what does '5 minutes' actually mean?

 

[LordAizenSama]

5 minutes means it was slowed down by 5 minutes. Or made the day 5 minutes longer. 'In that instant' juat means it happened immediately. The date does not matter at all as it was still 5 minutes. What you're saying is just semantics really. How the author wants to tell us whats happening is up to him.

Necrobump, since I want to know how Accel got High 6-A.

 

[Matthew_Schroeder]

Could have made a thread for it?

Necrobump, since I want to know how Accel got High 6-A.

Then make a thread, don't necro an old thread
