Goliath/Titan question

[GigaG]

Does anybody know how many G's Titan and Goliath pull on their infamous black-out helixes?

[DJeXeL]

I believe it's 4.5-5 Gs max.

[Loefet]

^ No, if you were talking about the bottom of the first drop then I would believe you, on a helix? Not a chance...

 

This is a common misconception, it's not only the amount of force that is exerted on you, but also the time that you are influenced by that force, that cause you to black out and eventually die. The shorter time the more force is required, and it works the other way around as well, the longer you experience it the lower the force have to be. A bottom of a hill passes pretty quickly which allow designers to design rides that have forces that exceeds 4.5-5 g's, on a helix on the other hand which take several seconds to ride through requires a lot lower force for people not to black out.

And by the sound of Titan/Goliath (and original I305) then these are at the limit of what people are able to endure. Still no 4+ g's that people believe they have but more likely less than 3 g's.

 

There is a pretty good graph on Nolimits-Exhange that shows the maximum force vs. duration it's exerted, which gives you a picture on what kind of maximum forces you would experience on a ride. Just time the length of the helix an look it up in the graph, and it will tell you the maximum allowed force for that duration.

 

 

Source of this graph is an article called "G-Force Lesson" at Nolimits-Exchange.com

 

Unfortunately neither me nor my brother haven't been to either of the parks with one of our accelerometers to get a log of it, but it's on our want list though.

Yeah, I need it for a nolimits coaster

[Loefet]

^ Then have a read on the page I linked in that case.

That's what I don't get about rides like this:

The first (and last) time I rode one of these, the operator was clearly running it faster than intended. I was standing there watching it and thinking, "No... Surely this can't really be as intense as it looks. That would be dangerous", but then my curiosity got the best of me, and I just had to try it out for myself, despite my poor blood circulation and better judgement.

 

Near the end of the ride, the operator shifted it into high gear, pulling what was easily over 3 g's for about 30 seconds. I was tensing up my whole body and pumping my legs the entire time just to stay conscious.

 

As soon as I got off that thing, I laid down on a bench to get the blood flowing back into my head. Then I headed straight for the Top Scan and got about 5 rides in a row to clear my mind of that horrific experience.

 

...Never, ever, ever again! I avoid that ride like the plague now.

[Loefet]

^ I doubt that it pulled over 3 g's for 30 seconds. Also it isn't a "static" force that you experience on a Helix, it's way more dynamic since it rotates in several dimensions.

It will produce a lot of lateral forces, most likely around 1-3 g's on every rotation (3 closest to the ground and 1 at the top) then the main rotation of the whole ride will most likely produce around 1-2 g's vertically due to the centripetal force. Sure the resultant force vector will be over 3 g's at times, but not for 30 seconds straight...

 

The graph I posted above is only valid for positive vertical g's. A human can withstand lateral/acceleration forces way better since the distance the blood will flow due to it is much less and it will still be spread out throughout your body, not drawn to your feet or head which is really dangerous.

[nannerdw]

^Yeah, maybe it's a bit of an exaggeration , but the center axis was definitely rotating much faster than what's being shown at the end of that video. I wish I'd had my video camera with me, because it was literally the most intense ride I've ever seen. I guess that's why it's called "Extreme." It was certainly too extreme for me, lol.

 

Also, the lat. g's really weren't that high with the arms out at full swing, probably about the same as an Orbiter.

It depends on the clientele. Goliath can carry as many as 30 G's.
