I have seen thousands of fractured .......... fractures that bother me the most in the Dyatlov group are the rib fractures... These are not easy fractures to accomplish........
What strikes me most about Dubinina's fractures were that there were essentially 3 fracture lines across her ribs. Ribs 2, 3, 4, and 5 on the right side..............
............. indicative of a tremendous impact, maybe a long fall whereby she landed flat on her chest/stomach. I am attempting to find any other cases of such fractures...........
Hello ! RidgeWatcher and Frankie, so you've had a "chance" to observe in reality
human bone fractures.
I am currently working on my hypothesis N°2 which is inspired by Eduard Tumanov
, in his "fight against outsiders version", by Aleks Kandr
) and by several others such as Per Inge Oestmoen
...etc, according to the bone fractures of the 4 du den are not due to falling.
Then, 3 aggressors, armed with blunt objects and without firearms, would have reached the tent, around 8 am on February 1, 1959....
I know how to quickly make effective blunt objects by pruning tree branches with a knife and a hatchet. This can also be called a bludgeon or a two-handed club
, with one end having a diameter of 3 cm for a good hand hold, while the center of gravity is close to the other end which is much thicker.
- Typically length=120 cm, weight=4 kg - strongly depending on the user's stature and musculature -
However I have no certainty because I have neither human skeletons, nor corpses to make sure how bones can be broken.
••• I would be glad to have the opinion of experimented or professional members of DPI with real knowledge about human bone fractures. •••
For me, the blunt objects, which Tumanov talks about ( https://forum.dyatlovpass.com/index.php?board=53.0
), are pieces of birch trunks that are available for free and in abundance in the Taiga around Vizhay.
Theoretical study of inelastic shocks is difficult so in a first preminilary approach, I content myself with estimates of the energies involved with blunt objects of length 1.20 m and weight 4 kg.
• Potential energy of a 4 kg mass at 3 m altitude = 120 joules
• Muscular energy provided by a aggressor-beater = (2.5)*120 = 300 joules --- (factor 2.5 to be discussed)
• Total energy corresponding to a single club hit = 420 joules
A bludgeon blow has a breaking power comparable to the impact of a birch wood sphere, 23 cm in diameter, moving at a speed of 51 km/h.
(birch wood sphere ---> diameter=23 cm || weight=4 kg || speed=14,1 m/s || kinetic energy=400 joules)
According to my hypopthesis N°2, there were probably 3 aggressors: 2 beaters and an organizer carrying a lighter baton.
I also suppose that each aggressor-beater cannot repeat more than 10 strokes in a row, because then the aggressor is forced to stop momentarily because he is tired.
So Dubinina and Zolotariov, once lying stunned on the ground
, could have received 20 separate blows to the chest from two blunt objectswhich corresponds to a total energy of 8 kilojoules
= 2*10*400 joules.
Now my question is: what do you think about the possibility of performing Dubinina and Zolotariov's rib fractures with blunt objects ?
The objection, sometimes put forward, of the absence of external trace does not seem to me to be relevant:
a) - The blunt object striking has a very rounded, almost spherical shape.
b) - The state of rottenness of the bodies of the four of the den was advanced when they were examined and no conclusion was possible.
