What makes an inversion

Yes, in my question marathon on this site, I have asked about tallest inversions hyper coasters and more. Now what make an inversion. I mean seriously. Millennium Force has an "Over banked Turn" of 122 but is that an inversion. If it isn't that means Mantis' sloping loop isn't an inverstion because it isn't straight up and down. What do you think?

Number 1 And Only Cedar Point

It's the thought that counts, i.e. B&M thought to call the inclined loop an inversion, while Intamin thought not to call the overbanked turns inversions.

i have always said that to be iverted, it has to at least be 170 degrees.

speaking of inclined loops, what if you had a double/triple helix, and turned it upside down?
It would be all loopage!

I think to be inverted you must be 180 no more, no less. That is why I think while the Inclined Loop is cool IT SHOULDN'T be considered an inversion.

I agree with Everdred. I think the best bet is to just follow with what the coaster manufactures say.

You build it, I'll ride it

If you ask me, at any point in which your body is angled downward is an inversion. Thus being that 91 degrees is in fact an inversion. Yet, when you really think about it, who cares anyway?

I am with Revolutionary, If a ride is fun, its fun. Who cares if its inverted or not, Or a record breaker or not.

Since I enjoy splitting hairs...

banked turn- from 1-90 degrees

over-banked turn- from 91-135 degrees

inversion- 135-180 degrees

My reasoning... 90 degrees is vertical, right? So, halfway between vertical and upside down is 135 degrees. (90+45=135) Therefore, 122 degrees is nearer to vertical than it is to upside down, not an inversion. A turn that hits 145 degrees would be nearer to upside down than it is to vertical, yes, an inversion.

The overbanks on MF did not feel like I was upside down, the incline loop on Mantis (&RR) does feel like I am upside down.

Gotta ride 'em all!

Amen to Soggy. Those overbanked turns do not feel like you are upside down at all.

everdred: I am a member of a 'coaster-talk' email list and we recently had this discussion. One of the list members was a ride op on Kraken down at SWO. He said that in the official manuals printed by B&M, they specifically call dive loops, vertical loops, cobra rolls, batwings, flatspins, and immelmans inversions. HOWEVER, there was no such designation for the inclined loops. Therefore, one cannot be 100% certain that even B&M thinks inclined loops are actual inversions.

it seems it should be considered an inversion where your but passes over your head. either front to back or side to side.

Am i right when i say that a hyper or giga coaster are not allowed any inversions ? If so, maybe this is a possibility for why intamin did not call their overbanked turns inversions.

If they called them inversions, then they would need to install OTSR too.

Not exactaly, Swartzkopf(sp?) have loops minus OTSR. I agree with Everdred

Actual the definion of inversion is the exact opposite of something. So it must be 180 degrees.
