Scaling Lifting Strength to Catching Punches

That's cause this is the first time this sort of thing is being addressed in a CRT to most of our knowledge, so nobody bothered to think about that lol
Its actually used in quite a few profiles, i was more susprised that people didnt know it was a thing
 
I mean, you see someone with stellar tier, punches someone yet the they don't budge or something , depending on how the scene is depicted, he should get dura and LS but I really don't know why
 
Really? Well ****, that's news to me. Mind giving a few examples if you have any?






 






James Heller's Class M is actually an upscaled giant-head-ripping feat, not a punching one.

Big Boss's feat actually involves deadlifting the Coocoon above his head, not just stopping it dead in its tracks as it tries to crush him from above.

Toshinori Yagi doesn't just stop at punching the block, he also provides an upward force to keep it from falling into him and with Deku ultimately gives it one last push with their fists. Also I think we already had a thread for this specific topic where Therefir defended the calc.

MCU Hulk also has a feat like this where he punches a massive Leviathan but it isn't enough so he has to push it with his fist like in a Wrestling match to halt its advance gradually

Difference between these feats and RWBY is, these feats actually involve calculating the mass of the object beforehand.
 
Deku and All Might don’t even have LS based on the cube, wtf. How many times do I have to say that, it was literally rejected because it was a punch.

Its literally linked to him punching the floor and gettig Class M out of it

Meant to remove him, i was referring to Raiden's feat

So does Yang

Yang didnt punch it though, and she halted it immdiately

Mkay, i can do that

James Heller literally scales to this as per his LS description, I'd know, I evaluated it.

Meant to remove him, i was referring to Raiden's feat

Agnaa considered the acceleration timeframe in Raiden's feat to be too short of a timeframe as the standard "force= mass times acceleration" can inflate results if the timeframe required to stop the object is depicted as too low (Which I personally don't agree with and I myself consider the feat valid), but he'd still scale to the mass of the Submarine itself which is Class G.

So does Yang

I saw the feat, yeah, Yang grabs the fist and is more direct than All Might, I think the only issue they have now is the scaling of that newtons-force value, whereas in All Might's might, the mass of the cube was calc'd beforehand and there was a timeframe and KE calc involved. Not sure if that would work in Yang's metal punch blocking case.

Also, y’know, All Might doesn’t scale to the cube for his LS. So that point is moot.

Except he didnt fully stop it and it crushed him

The forc of its punch was calced

Well ****, I just checked All Might's profile, he scales to an LS strength feat way higher than that Cube he destroyed with Deku.

My other points still stand tho.

The forc of its punch was calced
I think I get the issue now.

Whereas most of the other calcs calculate the mass of the object and their speed and acceleration to get the LS values first, your calc uses the impact strength required to move concrete in a horizontal fashion (As in, punching it in a horizontal direction), which is a tad bit different from what Deku did (Where he crushed it in his hands and it being different from a punch). That's prolly why people are taking issues with this from what I can see.
 
Except he didnt fully stop it and it crushed him
He briefly stopped it before getting overpowered by it slowly accelerating back into him (In the scene the submarine only advances by mere centimeters before Raiden gets crapped on), it's like stopping a bull but then the pull pushes back and you're losing your ability to slowly resist.
 
If deku crushing a rock can be used as lifting strength then this should too

Just saying
Ye but Yang's feat is a bit different than Deku's, since Deku has to envelop the rock in his hands and apply pressure to slowly crush it, whereas in Yang's case it's blocking a rapid punch in a single horizontal direction.

Okay but another character in RWBY, Yatsuhashi, has the same kid of feat and it was determined to not be scalable

Basically in this case, you'd need to figure out the mass of the metal arm, figure out how fast it was going when Yang stopped it and then you can figure out the deceleration value from there (Top speed to screeching halt). Then slap the mass and acceleration values into the classic F=ma formula and you'll get your answer.
 
I agree with KLOL, orange, and weekly with this, catching a punch and stopping it dead in its track should have the character's LS scale to the other person's SS, unless it is one of those weird cases where they stop it and kinda block it at the same time
 
brought this up is a crushing feat
It's a crushing feat translated into a force calc from a punch because of a sudden impact.

We already do that. This thread is about calcing the force generated from a blow based on the shocwaves from it or total arm movement.

Yeah, that's the difference between the RWBY feat and all the other feats Weekly and I mentioned. Which also explains why people are having issues with it.

Regardless, I've already laid out the correct way to figure it out in case all else fails.

I don't think catching punches should be LS. Realistically, every single durability feat where the environment doesn't take a corresponding amount of damage should be a LS/AP feat, but most people would see that as taking things too far. And I don't think catching a punch with your hand should give LS, while catching a punch with your chest (i.e. no-selling a punch with zero knockback) or catching a punch with crossed arms (a block) wouldn't. So I think for consistency, these sorts of feats should just be dura.

Okay but why tho? Why would stopping a force equivalent of an amount of mass by pushing back against it with your hands not be a feat of lifting strength?
 
If we went ultra-literally with IRL physics it would be, but so would every dura feat where the environment takes less damage than the punch's AP. This is especially easily demonstrable in cases where the character is not knocked back at all.

But since we don't do that, and that it'd get a bit silly to do that, we shouldn't give it for either case.

I disagree, they should scale in cases where Character A has a stated/calc'd LS (Like being Stellar for moving stars and stuff) and Character B catches that punch and then they both wrestle with their fists, or when characters stop a charging car / train / whatever type of vehicle dead in their tracks, they'd scale to the mass of the vehicle at the very least.
 
I've been told a lot more times than once that we don't treat dura feats along those lines as LS. If we treat them all as LS, then keep doing that. If we don't treat casual dura feats as such, then don't.

Your first situation is completely inapplicable because you added "and then they both wrestle with their fists", that obviously counts for LS scaling.

Cases like that don't actually scale to the mass of the vehicle because of the way the forces involved work. A vehicle's mass, for LS purposes, is applied downwards towards the Earth and only applies when lifting something up. For stopping a car/train in its tracks, you need to take its mass, and the acceleration the character is providing against it to give you the force involved. This can be less than the weight of the object (if the deceleration was less than 9.8m/s^2), or it can be more (if the deceleration was greater than 9.8m/s^2). I'm fine with using those feats if they slow it down by pushing against it, but not if the object crashes into them then goes flying elsewhere, or stops completely (especially since that massively inflates the calcs, as t goes towards 0, force goes towards infinity).

Yeah, I was talking about slowing down or stopping them quickly by pushing against the vehicle/object driving into them.
 
@Agnaa have you seen the clips in question?
No I haven't, I was told this was a general rules thing. I hope that my messages are enough for you to figure out how they'd apply to whatever specific cases you have in mind.

What hollowness do we assume for machines?
 
I did notice what KLOL said and kind of agree there could be case by case in mind. Blocking a punch from a giant character for example seems okay to get lifting strength to some extent from or if a character attacks by swinging a building sized sword and the like. But I do not think a simple "Character A is Tier X and character B consistently blocks his punches and doesn't even budge" should have their AP be divided by the length of their punch which will turn an energy calculation into a Newton's of force calculation that character B gets that treated as a lifting strength feat; that's basically calc stacking.

Another example is when Trunks effortlessly bench pressed Frieza's Supernova or Goku casually blocks Trunks' sword strikes using just his finger. Android saga characters would have Stellar Class lifting strength a long time ago by that practice. Or even a couple of 9-A characters blocking each others punches could get Class M results despite not having a single lifting feat surpassing Class 10. That's where some of the basic problems like.

I mean, Weekly didn't make the calc to get a joule value out of it, he got it from the actual IRL strength required to break concrete. The main issue is that it's rapid unlike most pushing LS feats involving toppling stone beams and such where it is slow.

As for the second statement, I think I already stressed that stuff like that would not work (Deriving LS from a joule-only attack that doesn't have its mass calculated beforehand), the character would need to have a separate LS value like lifting cars, buildings, stars, whatever, for that type of LS scaling to work. Like in the case of the Metal Gear feats where we have the object's mass calculated and whatnot to figure out the force and KE.
 
For trunks example, it's a good one for couple of reasons:
Let's say that we know how heavy the Supernova of frieza is [I'll just give it any number, it doesn't matter], let's say it's universal or infinite because why not. We see trunks physically lifting it, thus he would have universal LS, pretty good so far
And when trunk used his sword against goku, goku managed to block it. Good a dura feat
Buu~t you can also say it's LS, because remember trunks was using two hands, plus his sword was infused with ki, yet still not managed to make goku's finger move, it also stopped trunks sword from moving [trunks slashes his sword against goku's finger, but instead of pushing against the finger we see it drop dead in its track] thus meaning goku can stop Objects that have Universal weigh or LS if you wanna, in their track
It could be either way tbh, it just really depends on how you wanna see it
You can say
"Well he only tanks it so no it's not. LS feat, merly dura feat"
Or
"He stopped it form moving, thus using force [and his LS]to stop it and push against it, it's Dura and LS feat"
In these cases, the best approach would just do them both tbh, and if it creates problems in scaling later on [like character not preferring similar feats, failing to constantly perform feats in the same class or below] we get rid of it

If it helps the Paladin casualyl flips vars and trucks and is the size of a second story building
