Yes, doubling the compression depth of hydraulics would make them twice as effective. Would you bolt a second jack system to the bottom of the first? Or would you just take that second jack system and put it on the other leg? Okay, imagine you only had one leg with a jack system, but you wanted to get twice the benefit by adding to the hydraulics. You're failing to account for a few basic principles of physics. but it wouldn't be a standard powered armor hydraulic jack system, it would be a specially designed piece of equipment. On a side note, i would be inclined to allow something like hydraulic jack extensions that you could wear that would be designed to use your hydraulic leg jacks to absorb more damage. (so, for example, if you strapped your feet onto the shoulders of a suit of this armor, and managed to aim the armor so it lands feet down without dropping you flat on your face, then both jack systems would stack). as i said, it simply doubles the distance over which you decelerate, which quite effectively reduces the force further. i don't know that i would let them stack in power armor purely because if your power armor could stretch far enough to fit your built-in leg jacks, it would probably just put it's own (rating 12) hydraulic jacks in it.īut if you were falling on something that had the same hydraulic jack system which managed to land jacks first, and you also applied your own, i don't see any reason it wouldn't stack. I don't see why any calculations would be needed.Ģ jacks will give you twice the distance to decelerate over. Now, if you really wanna argue semantics, I'm more than happy to calculate exactly how much kinetic energy each jack system can absorb independently via physics and compare it to the handwaved values of ignoring 18m of falling (which would impart more energy) and come up with a house-rule value which adds diminishing returns to the extra systems, but realistically it isn't going to be that big of a difference. (Yes, there are rules for terminal velocity. And that's not even terminal velocity via rules. If you fall 184m - 18m for jacks and Freefall, you still take 85P damage.

I will admit, if you fall far enough (183.6 m, or 602.35 ft) to be traveling 60 m/s on impact (196.84 ft/s, 134.21 mph), you're screwed no matter what. The physics just do not match up, and the further you fall the crazier the disparity becomes. The rules are a linear increase of damage with distance, whereas the amount of force you have to deal with at the end of a fall increases exponentially with distance. If you don't do that, the rules just don't work. For the sake of sanity and simplicity, we can handwave that away by saying that the jack systems are designed to operate under standard ranges of weights - troll sized jacks will be designed to accomodate average troll weights, for example armor jack systems take into account the added weight of the armor stuff like that.

Now, how much that hurts is dependant on your weight. You've also been in the air for less than 2 seconds. So when you hit, you're traveling at 18.78 meters per second, 61.62 feet per second, or 42.01 miles per hour. V = final velocity u = initial velocity s = displacement (distance) a = uniform acceleration Yeah, I like this argument right here the best. Your main body is still mostly going from a very high speed to a very low speed in a very short amount of time. I mean if you are going from 60m/s to 0m/s over a distance of a foot, there is a limit to how much of that can be absorbed purely by your legs, regardless of what your legs are made of or have in them. Both would require you to make the same motion, and it is questionable if both would be able to operate at the same time, and even if they could, there is a limit to how much you can break the fall. I figure the main reason would be that it would be difficult to have them work in tandem. That said, I did think of what you said slightly after I'd posted, but decided to leave it hoping no one else would notice. It is one of those things (For the multiple ware thing) that is so assumed you don't even bother mentioning it. But I also don't think there is a rule that states you can't get 2 muscle toner wares, or 2 of any other ware.

I don't think there is a rule that states they don't stack. If there is a rule stating they do not stack, please point it out to me, because logic and physics dictate they should stack. Therefor, two separate sets should absorb the sum of their kinetic energy absorptions.

You then put on power armor, which has external hydraulic jacks.Įach set of hydraulic jacks absorbs a certain amount of kinetic energy when it activates.
