Back to the question of deceleration: My goal here is to make the vertical distance of deceleration as small as possible without harming the body. To that end, would it be possible to do the following: -Attach a bunch of tiny, hollow cylindrical 'wheels' to the bottom of the system. Through...

Alright. So, how does one avoid the propagation of shock waves through the body? Literature search hasn't done much for me, or maybe my Google-fu has dropped considerably since the last time I researched this. If I'm reading this thread right, so far there are established methods to limit the...

Very interesting. 3800g would indicate that with half an inch of deceleration distance, the maximum height one could fall with this setup would then be about 48 meters - not too shabby. I wonder what a shear thinning fluid would do here? Not out of any application to the subject at hand, just...

Alright then, I guess I can dig up some size restrictions, although these aren't really set in stone. Max dimensions would be 2.5 inches tall by 1.56 inches wide by 1 inch deep. What is an 'accumulator'? Also, I thought oleo struts stayed at a constant inner pressure with no load applied - why...

So, if rapid deceleration harms the body upon impact, is there any way to circumvent this? I had another thought where the person would be standing on some mechanical contraption that converted the downward direction of deceleration into a rotation - rather like an odd cross between a hamster...

I was wondering if anyone could assist me in building my own oleo strut or lead me to some detailed instructions, as I'm new to the metalworking concepts that I presume will be involved. Also, out of curiosity, how 'absorbant' can an oleo strut be built - that is, what is the maximum energy one...

Ah. So then, could this be extended to a human as well? Say, if an airbag was surreptitiously strapped to someone's feet and they were shoved off a cliff (for science, of course), and all their kinetic energy was absorbed, they'd be fine?

Extract energy from it? I don't quite understand...

Sure, I guess. It has absurdly efficient shock-absorbing gear that absorbs all the energy. Honestly, this is more of a conceptual question, so I didn't feel like an explanation was necessary.

I thought of this recently, and want to know if there's something I'm missing. So, say a very fragile object decelerates to a stop from a given velocity. For example, a free-falling object hitting the ground. But, all the kinetic energy is absorbed through use of some clever mechanics (assume...

In the product guide for "sorbothane", found here - http://www.sorbothane.com/blog/wp-content/uploads/2012/12/11-26-12-Sorbothane_SPG_11.2012_v4.pdf They claim that a 0.50"-by-4" square of sorbothane of durometer 70 can withstand a load of up to 2000 lbs. Now, I plan to use this for shock...
