So, basically, the premise is that our main boi, John Taylor throws a thing against the wall hard enough to break the bones of a living man, IE, he basically just threw something with the force to straight up break someone.
So, with that in mind, how to quantify? Well, with the powers of my bro Bambu on a certain sister site, it's easy.
So, what we need to do is find the weight of a man's bones. On average, that would be 15% of their body mass, which inof itself is 88.768027 Kilograms. 15% of that is 13.31520405 Kilograms.
The density of bone is 3.88 grams per CM Cubed, which would mean that the total volume would be 13.31520405 divided by .00388, which equals 3431.75362113402 Cubic CM for our volume.
To get the fragmentation values, we need to use the compressive strength of bones. To quote a site that I use because I'm too lazy to do my homework, "bone has a high compressive strength of about 170 MPa (1800 kgf/cm²), poor tensile strength of 104–121 MPa, and a very low shear stress strength (51.6 MPa)"
So, low end is 51.6, mid is 104, high is 170. Plugging those all into our volume gets us....
Low End: 177.078486850515432 Kilojoules, 0.00004232277410385 tons of TNT, Wall level
Mid End: 356.902376598 Kilojoules, 0.00008530171 Tons of TNT, Wall level
High End: 583.398115592783 Kilojoules, 0.00013943549607 Tons of TNT Wall level
Wall level all around, but hey, a bit above the 14 Kilojoules baseline.
Also note, you can apply this to any bone you want via finding the weight, applying density in reverse, and applying the shear strength.
