RE: Near-Topic: G forces

This is true, it was rocket sled deceleration experiments during the 50s
(Eyes Out Gs).	Subject took approx 40 gs eyes out.  Complained of chest
pain.  Later experiments and autopsies show that the aorta will be
ripped
free from the heart at approx 40 gs.  Postulation is that his chest pain
(separate from chest straps markings etc) could have been damage to the
aorta just short of ripped free.

I think I have the info at work, will try to get it for tomorrow.

As with all other important questions, it depends.  If you are asking if
people
can inhabit high g worlds, there is no data.  Fighter pilots are trained
to
endure short periods of about 13 g's.  Murphy coined his law after a
failed
experiment to measure effects of short duration, hard accelerations on
the
human body-- all sixteen accelerometers were fastened to the harness in
the
wrong way, but analysis of the film allowed Murphy to calculate that the
subject endured forty g's.  I apologise for not being able to cite a
source,
but fifty g's is what they aim for in frontal automotive collisions.
