About the G in an accident, I had read or heard a while ago that plane crash subjected its occupants to 50 to 80 g...

However, the human body does not support more than 15 to 20 g for a very short time ... this is why the survival rate is very often zero ...

Yes, an ejection fighter seat produces up to 20g, and pilots are only allowed a limited number of ejections before being reformed ...

[HS]
For comparison, the acceleration of a shell in a cannon is around 30 g. It goes from 000 to 0 km / h in 1300 meters ...

part of the human body supports much more than 80g

when you punch your fist on the table, the skin that touches the table undergoes a number of g close to infinity ... but there is only the surface of the skin ... the deformation of the tissues means that the first bone undergoes a reasonable number of g

we can come out alive from a fall or the feet that touch the ground will take a huge number of g ... or the energy will be dissipated by breaking bones, but that the vital parts will not have exceeded the limit

the problem is that a broken bone does not absorb much, all the muscles must be contracted to effectively absorb a shock ... hence the completely random result of an accident

like the driver who saw the blow come unscathed, and the passenger caught by surprise dead

I like "close to infinity" : Mrgreen:
