on breaking bones

[Rivarstar007]

for a feat this common, a 300-9000 J range is extremely unhelpful, also, why exactly are we using as reference the bones of a 52 yo? I mean, I'm no orthopedic but that's like using the slowest gun to determine bullet-dodging. I've seen people using breaking, dislocating, breaking by the joint and twisting interchangeably, when the study rlly what it did was apply force with 3 prongs, 2 to hold cutted bone pieces in place and one doing the fracturing thingy, so none of the others should really count as breaking. I understand that angle matters because bones are anisotropic, but really? 300 joules for 5 degrees and 9000 joules for 50 degrees? that's all? for what a could find, fracture energy of bone ranges from 5 to 30 J/m2, 100 to 300 for bulk cortical bone link here, no idea if that's useful.

because bones are anisotropicful.

They are what?
What even is this word?

Anisotropic is when a physical property varies depending on direction.

Thanks!

Well, awhile ago, I last saw it come from a calc group member (but it could obviously originate futher back). But I'm planning to revise the specifics of the feat.

Breaking a bone depends on the context of the verse+character in-question, the angle of attack and what bone you're breaking.

• If you've just fractured the chest or face of a reg. person, it would be around 10-B to 10-A since people's punches don't reach 9-C levels of energy. We're forced to work around the oversimplification of our tiers at 10-C to 9-C.
• But if you say... regularly preform peak human feats and fracture a leg of a reg. person (one of the strongest bones are there). It would count, but I don't think it would make sense to say breaking a femur is 10-B+ if it's the strongest bones of the body. Not to mention bone is made up of 3 types of bone tissue and the 100-300 J part is only factors a part of a bone rather than the whole.

A 52 yr old isn't too far from a regular person's durability since everyone practically walks (which bones regularly withstand).
