One Punch Man Upgrade to High 7-A (based on new chapter)

[DbzDB2]

In the new chapter of OPM that was released today, Psykos compresses a ball of stone to less than half of it's original radius .

How big was the concrete ball ? It's radius appears to be 4 floors tall. And the floors are around 4 times the height of Saitama. So 1.75 x 4 x 4 = 28 meters radius. So the ball of concrete is around 200.000 tons.

But whats more impressive is the compression. How hard it is to compress concrete? Concrete's average elastic modulus is around 27.5 Gigapascals(GPa). This means its bulk modulus (material property about reducing volume) is around 15.2 GPa. If she crushed it to 14 meters radius (%87.5 volume reduction) she would need to apply a pressure of 13.3 GPa or 1.355.760 tons per m^2. With a surface area of 2463 m^2 she would need to apply a total force of over 3.3 billion tons.

This is actually a lowball considering the fact that Psykos actually compressed the ball into less than it's original radius.

IIRC, 3.3 billion tons of force is in the High 7-A range.

Tatsumaki casually overpowered Psykos' attack, but she doesn't get an upgrade since she's already High 6-C Also, Psykos was able to increase the gravity around Tatsumaki 300x. I don't know if that warrants an upgrade though.

I would post it here if you haven't already, so it can be evaluated.

 

[The_Calaca]

I'd post it in a blog instead.

 

[Andytrenom]

Pretty sure we don't use force for Attack Potency just energy

When we talk about "tons" it doesn't refer to how much force was exerted in a feat it refers to how much TNT would be required to release the same amount of energy as the feat. I don't think the results you've calculated are actually high 7-A.

 

[Hellbeast1]

We just use tons of tnt

 

[Spinoirr]

Someone calc this

Because it may need a recalc

 

[Qawsedf234]

Tons of force does count for lifting strength, but like Andy said you need the energy required to compress something for actual AP.

 

[DbzDB2]

So what can we do to figure out the AP of this feat?

 

[Spinoirr]

Well get a calc member here for one

 

[DbzDB2]

Please do so.

 

[PaChi2]

Aint this a lifting strength feat, tho

 

[DbzDB2]

Aint this a lifting strength feat, tho

Compressing a ball of rock isn't lifting strength

 

[PaChi2]

Compressing a ball of rock isn't lifting strength

Considering it is done through TK, the same force applied to the ball can be used to lift an object. So you can count it. Buuuut, whatever.

For the record: 3.3 billions of tons = 3.3 x 10^12 kg. Class T. It'd upgrade tatsumaki.

 

[Qawsedf234]

Well

• 1 Newton = 1 Joule/Meter

• 3,339,236,880 tons of force = 29,707,331,336,182.06 Netwons

• 29,707,331,336,182.06 = 29,707,331,336,182.06 Joules/Meters or 2.907e+13 Joules or 7-C

So assuming I didn't do anything wrong this would be a lifting strength upgrade for both, but not a AP upgrade.

 

[Qawsedf234]

Wait I was indeed wrong. Its Newton-Meters that directly convert into joules

• 3,339,236,880 tons of force = 32,746,727,349,250 Newton-Meters
• 32,746,727,349,250 Newton-Meters = 32,746,727,349,250 Joules or 3.274672734925e+13 Joules or 7-C

I guess its more support for casual Town level OPM

 

[Andytrenom]

The calculator was for converting tons of force ''' meter''' to newton meter. You obviously cannot convert force to newton meter directly when nothing else is known.

 

[Qawsedf234]

OP's math already assumed it was by meters didn't it?

she would need to apply a pressure of 13.3 GPa or 1.355.760 tons per m^2. With a surface area of 2463 m^2 she would need to apply a total force of over 3.3 billion tons.

If its supposed to be 1,355,760 per meter then the number would be much lower.

 

[Callsign_Castle]

You solve this using work. (I think)

Work = force x distance, the answer is in joules.

 

[Andytrenom]

Pressure is force/area

Pressure x area gives force which seem to be all that was calculated in the post.

 

[Andytrenom]

@Callsign Yeah, when converting force to energy work is normally what you use. The only thing is we have to figure out what the distance is.

 

[Qawsedf234]

So how do you think it should be tackled? I don't think it'll serve as anything more than a lifting strength upgrade though.

 

[Callsign_Castle]

Well assuming the distance is the radius, the answer is 4.11e14 joules.

 

[Qawsedf234]

The chapter. Pages 2-4 is when the feat happens. I think the rocks around Tornado is the "final" radius of the concrete before it was exploded out.

 

[AguilaR101]

@Callsign Yeah, when converting force to energy work is normally what you use. The only thing is we have to figure out what the distance is.

The difference between the starting and ending radius of the sphere would work, just multiply that by the force to get energy in joules.

 

[Andytrenom]

I was thinking just that. Thanks.

 

[Qawsedf234]

Not super offical but I know that some guy forever ago used some anime posters to get a height estimate of 142 centimeters for Tornado .

 

[Andytrenom]

Does she not have official height?

 

[Qawsedf234]

Nope. The databook lists her height and weight at "Undisclosed". Its why Blizzard and Prisoner also don't have an official weight, since they didn't allow them to be put in the databook (as the first section is from an in-universe perspective).

EDIT: Her databook page. Her weight and height are listed as "µ£¬Õà¼Úûï" which means Unpublished

 

[Andytrenom]

I don't think comparing posters is a good idea, at least use a picture where she and another character are side by side.

 

[Qawsedf234]

True. I think there's an image of her standing next to Child Emperor who has an offical height. I'll try to find it.

 

[Qawsedf234]

Oh hey I found it super quickly. From Chapter 90

• Her standing next to Child Emperor

• Child Emperor is 135 cm tall officially

Dunno if there's a better one, but that's the first that came to mind

 

[Qawsedf234]

I think I found a better one here. They seem to be on the same plane unlike the first one where Tornado was a bit behind CE.

 

[Andytrenom]

I'm not sure if they are actually side by side there.

 

[AguilaR101]

Also before any calc is made we need sources for the Bulk modulus of concrete and we need to scale the size of the sphere as well.

 

[Qawsedf234]

I'm not sure if they are actually side by side there.

In the first image or the second one? Because I agree that she was behind him in the first, but the second they look to be on the same plane.

 

[Andytrenom]

@Qaw First one

 

[Andytrenom]

Also taking them to be of equal height will be better than trying to scale imo, since we don't see either's full body.

 

[Qawsedf234]

Yeah that's probably the best option.

 

[Qawsedf234]

In the old calc for Emperor Nova they found that the height of the doors are like 5.5 meters. We could use that to find the thickness of the floors and the diameter of the sphere.

 

[DbzDB2]

Can someone recalc it then?
