martinb Posted July 2, 2006 Share Posted July 2, 2006 This was first mentioned when someone talked about how high the G's were on Boomerangs, well theire stats say 5.2G's which I found to be quite high, but take a look at this: http://www.rcdb.com/id1481.htm 6.3G's!!!!!!!! I thought/heard that positive G's over 6 would make your eyes gouge out of your head and your nose bleed, I didn't make that up, I heard it on a coaster programme. Anyone know of any other coasters with high G's like this? -Martyn Link to comment Share on other sites More sharing options...
Director_Guy Posted July 2, 2006 Share Posted July 2, 2006 Eyes gouge? Uh....fighter pilots pull like 8 G's.....g dog. Link to comment Share on other sites More sharing options...

jmccalip Posted July 2, 2006 Share Posted July 2, 2006 You only pull those G-s for a split second. Not a big deal. Link to comment Share on other sites More sharing options...
Calaway Park Posted July 2, 2006 Share Posted July 2, 2006 http://www.rcdb.com/id193.htm Mindbender... It used to have 6 g's but they removed a car after the accident. It pulls 5.2 now... still pretty good. Link to comment Share on other sites More sharing options...
ShoubraStreet74 Posted July 2, 2006 Share Posted July 2, 2006 Hmmm.. Worm should know something about Tower of Terror. Anyways, I think it's mainly an issue of how long the Gs are sustained. Even a relatively low amount of Gs for a long amount of time can cause a blackout/greyout. Just look at Goliath at SFMM; I'm pretty sure the helix pulls no more than 4 Gs, but it just keeps going for a very long time, and many people grey out on it. I don't think 6 or more Gs for a split second would be a risk to the human body. The problem seems to come when high Gs are sustained for a long period of time. As for the eyes gouging out and such, that would only happen if the Gs were pushing in that direction right? If the Gs are from a pullout or helix it should just pull everything down into the direction of the chair. Well, it's something to think about.

ats86 Posted July 2, 2006 Share Posted July 2, 2006 Moonsault Scramble pulls 6.2G's, but it's no longer operating. http://www.rcdb.com/id1292.htm Link to comment Share on other sites More sharing options...
Worm Posted July 2, 2006 Share Posted July 2, 2006 I've ridden Tower of Terror time and time again and the feeling is really amazing. its my 2nd best coaster cause of the g's. (my first is anaconda) the g's isn't really so bad, i bet its like a 1000th of a split second. PLUS: Anaconda has long sustaining g's, seeing that is maade by giovonala. The helix around the fake rock is absoltely insane! Gold Reef City has sent me an e-mail asking me to be on the 're-opening' day at the end of the month. They've also asked me if i wanted to make an POV, but they also said that would be on my own risk. Link to comment Share on other sites More sharing options...

onemorenightwithyou Posted July 2, 2006 Share Posted July 2, 2006 Eyes gouge? Uh....fighter pilots pull like 8 G's.....g dog. Yeah, but they wear suits that protect themselves from it. Six G's is pretty much what most people can handle without any protective equipment. That's why planes such as the F-16 have computers... to limit G exposure...

RCfanatic Posted July 2, 2006 Share Posted July 2, 2006 Wow i didn't know a Boomerang pulled 5,2 G's! The strongest forces on a Boomerang i ever expirienced were in the front seat when going backwards thru the loop, on the top of the loop you get pushed into your seat, but i thougt i'd be like 4 G's or something. Anyway, this actually makes me love Boomerangs, unfotunately the front rows are the most popular with the gereral people. The Typhoon at Bobbejaanland has a maximum of 5 G's, the most intense part is the first drop into the loop and the loop itself so thats probaly were you get the 5 G's. www.rcdb.com/id2229.htm I don't think there are many coasters going over 5 G's, but i guess its no trouble if their not sustained...

HCOSurfer90 Posted July 2, 2006 Share Posted July 2, 2006 On Supercoasters on the National Geographic Channel, they showed men going through a g-force test. None of them wore those masks and they had to pull at least 10 g's (I'm pretty sure) for a sustained period of time. So I'm pretty sure g-forces WILL NOT gouge your eyes out.

IwantRevenge Posted July 2, 2006 Share Posted July 2, 2006 ^ to much negative g's can gouge your eyes out.' http://www.coasterforce.com/index.php?categoryid=185 right there is everything you need to know aobut the cuases, and effect of g's Thank you CF.

eskater132 Posted July 2, 2006 Share Posted July 2, 2006 Titan at SFoT pulls 3.5 POSITIVE gs on the "extra helix" that makes titan sooo much better than goliath at sfmm Link to comment Share on other sites More sharing options...
redunzelizer Posted July 2, 2006 Share Posted July 2, 2006 Folks you are (again, because this has been discussed so many times...) completely missing the point! The G-forces' impact and experiece (aka "feeling") will heavily depend on *duration* of these, as well as on *change rate*. Even that coasterforce article miserably fails to mention that, ( http://www.coasterforce.com/index.php?categoryid=185 ) at least i did not find a single note on duratiuon / change rates. You can safely pull 6.5Gs for fractions of a second, but you literally could kill someone with a mere 2.5 Gs, in case exposing him to such a force too long. Also, any *alltoo sudden changing forces* will result in whiplash or worse. Additionally, forces measured on the train/car itself may *not* resemble the actual forces acting on your body parts, since human tissue can have a big relaxation effect under certain instances. Your "G number play" should therefor be considered quite useless. just my two nasty jerks, redunzelizer P.S. another quote from coasterforce (on lateral forces): "Riders bodies are jerked sideways and this is why Wild Mouse rides are so painful." Huuuhh? Wild Mouse rides?? painful??? This finally leaves the impression that said article's writer is an incompetent wimp. Link to comment Share on other sites More sharing options...
Golfie Posted July 2, 2006 Share Posted July 2, 2006 I just did an inquiry based research project on this.... at 6 g's, you could black out :O ^ However, if it's only for a split second, that won't do much. When you drop into a chair, you pull about 10.8 g's - food for thought! Link to comment Share on other sites More sharing options...
Worm Posted July 4, 2006 Share Posted July 4, 2006 Most costers top g force is around 4.5 I've yet to ride a coaster that makes me feel like blacking out... PLUS: High g forces is also good for another thing; longer drops! think about it. Sheikra's VERTICAL drop, is probaly around 100 feet. (i'm talking truly vertical, not going into vertical) but probaly pulls around 4-something g's. Whereas Tower of Terror has a VERTICAL plunge of around 110 feet but pulls a jaw dropping 6.3g. I'm not saying ToT is bette than Sheikra, cause it obviously ain't, but i'm saying that ToT has a longer vertical drop than Shakira. Link to comment Share on other sites More sharing options...
methylene Posted July 4, 2006 Share Posted July 4, 2006 The only coaster I've ever greyed out on is in fact Titan at SFOT. It has high sustained Gs over several sections and sustaining Gs to the point of losing your vision isn't fun. It's the ΔGs that is fun to me. Worst hyper I've been on.

I would say its down to how 'tight' the incline from vertical to horizontal is, all the Dive Machines have really big, long inclines, I don't know what its like on the Tower of Terror, but I would imagine its pretty tight.# You can't really pull 6G's from falling vertically face down.

You don't pull any more than 1 G free-falling. With track friction, it is slightly less than 1 G on the way down (Discounting S&S towers which actually push you down). Positive G's are experienced as the track goes from vertical to horizontal, as martinb explained, or in the case of drop towers as the brakes are applied.

Free-falling would be 0g Equivalent to 0g, yes, as your inertia isn't encountering any resistance. You are still being pulled down at up to 9.81 m/s^2, however, which is 1g. The point, of course, is that you don't pull positive G's on drops. Matt Link to comment Share on other sites More sharing options...

The point, of course, is that you don't pull positive G's on drops. Matt I should clarify because I said "pulled down at..." which although illustrative isn't technical. On ground you experience 1g due to the ground itself pushing up on us to counteract gravity (which is you being accelerated at 9.81 m/s^2 into the ground). In a freefall, you're still being accelerated the same as on the ground but nothing is there to push back up on you so you feel 0g. Matt Link to comment Share on other sites More sharing options...
