Tearing An Arms - Class 5 or Class 25?

Flashlight uses an unreliable source.

First calc is eh. You should use the cross sectional area instead of the full area. You should also preferably use shear strength. That imo would make the calculation better. The calc simplifies the process though so, yeah, do with that what you will.

I could've sworn there was already a thread for this, and it ended with the argument that with each calc worked depending on how X feat showed the arm tear

Maybe I'm misremembering
 
To start, I don't see why people jump the shark and call Quora an unreliable source. What you're supposed to do is check the credentials to see how reliable the answer provided is. If it came from a mofo with a doctorate in the field matching the needs of the question asked, then that's an instant reliable answer; no need to be conspiratorial about that.

I have pointed out beforehand that the question came from high school physics, which I've added that high school stuff is prone to juxtaposition unlike university resources and research studies. After all, the purpose of the blog I've made was to show that the idea of ripping an arm off isn't exactly a one-size-fits all deal, and I find it questionable how the OP just picked an answer and rolled with it. Throughout the blog, I have pointed out a variety of sources, including a Stackexchange discussion about the same topic, the drawn-and-quartered execution method (real-life instances of the feat in question), and the same university source that used the 200646 kN figure used in the first blog linked. It was not meant to be used for cherrypicking; it was meant to be used for nuance.

I also think it's a little questionable that Vzearr claimed my calculations are wrong when I properly used elongation, which is the mechanical term for how far something can go past its original length before breaking. As such, it would make logical sense to use elongation to determine the maximum distance of which a force would have to been applied for before the object breaks. If a 10-centimeter object has a 50% elongation, that means it can go up to 5 cm before breaking. Typically an arm is pulled from one direction, meaning the force would have only gone in one direction. You're not going to get the shenanigans you get from pulling from both directions. Keep in mind, tension (the tensile strength stuff) is used because the feat typically involves pulling limbs outwards, not sideways like you're using a cheese grater.

For the record, I used the muscle lengths as that is the direction the force is acting on. I obviously didn't use the joints because frankly, anyone who practiced contortionism can pop a limb out of its joint including shoulder joints.

Ultimately, I think this stems from poor readership that led to cherrypicking, and I sincerely hope you guys actually read into it more.

Tl : Dr Read into things further than the first paragraph. You missed a whole buncha stuff.

Credentials on Quora are self-reported, though, aren't they? So I think it's generally best to avoid using it, we're taking a stranger at their word on the Internet at that point. That alone doesn't discredit your calc, but I don't want to support the idea that we can and should be using Quora because they say they are legitimate.

BTW, what do you think on using the horse end? That one more or less doesn't rely on Quora.

It basically came down to the following:
  • The speed of the tear
  • Was it all torn at once or did it get torn over time
  • What direction the arm tear happened in
The highest result was a horizontal tear that removed the arm all at once quicky. The lowest result is a vertical tear that resulting in some parts breaking off earlier than others.

It's like the spine rip stuff, it's only Class K if you start at the neck and remove the spine upwards all at once. If you start at the back or do it slowly, it yields far lower results.

In what sense? The calculations I've made on my blog primarily is based on pulling along the length of the muscles.
