teenageninja Posted February 28, 2003 Share Posted February 28, 2003 Ok coasterguy your not making scence on where you said "Or just have it where the highest swing is due to the zero g" that makes no scence we would need something to cover the whole are because once you go past vertical things start to fall.

Stitch Posted February 28, 2003 Share Posted February 28, 2003 No they won't due to the force pushing on them. Quote Link to comment Share on other sites More sharing options...
Losing Streak Posted February 28, 2003 Share Posted February 28, 2003 if you take a bucket full of water and swing it around, it won't fall out due to g's. At the top of the swing, there are no g-forces, and as such, it is an optimum time to lose things from your pockets, i.e. wallets, pocket change, cell phones, and the like.

Coasterfan Posted February 28, 2003 Share Posted February 28, 2003 The restraints on Vortex hurt your collar bone because they aren't OTSRs at all. They're horsecollar restraints. Quote Link to comment Share on other sites More sharing options...
pki_guy Posted February 28, 2003 Share Posted February 28, 2003 Face/Off has OTSR's. Horse collar restraints are more "barebone" things. just enough to hold you in. Quote Link to comment Share on other sites More sharing options...
Shaggy Posted February 28, 2003 Share Posted February 28, 2003 "The restraints on Vortex hurt your collar bone because they aren't OTSRs at all. They're horsecollar restraints. " Last time I checked, they went over my shoulders IMO a horsecollar and OSTR is a "like" term... same thing. As far as the positive/negative g thing..... A positive g is the force pushing you down in your seat when the gravitational pull increases. Positive G = the gravitational pull on your body is increased. A negative g is the force pulling you up out of your seat when the gravitational pull is contradicted. Negative G = the gravitational pull on your body is decreased. On Delirium for instance, you will feel positive g's at the base of the swing. At the higher points of the swing you will feel negative g's. Negative g's are more commonly referred to in enthusiast circles as "airtime." However, rides that have inversions or make arc movements like Delirium or looping coasters also rely on another force.... centrifigal force. Centrifigal force is an intertia that contrasts the gravitational pull on an object. So as you swing in an arc, or manuever a loop it pulls outward from all directions. That is what holds you in your seat while going upside down or holds change in your pockets when going fast through a loop. Using the bucket full of water idea... as you swing it rapidly upside down, centrifigal force holds the water in. But if that motion is slowed or halted, then gravity becomes the stronger force and the water will spill out. Centrifical force relies on speed and heavy inertia to override gravity. This basic idea explains how some coasters loops really pull enough force to not need restraints, while others do not pull enough and rely on restraints to hold riders in. Think of The Vortex... the vertical loops pull enough centrifical force to keep you in your seat. However the corkscrew is much slower so gravity takes control and your body relies on the restraint to hold you in. Shaggy Quote Link to comment Share on other sites More sharing options...
FOF Posted February 28, 2003 Share Posted February 28, 2003 One other little tidbit of useless information while we are on the topic of centripetal, and centrifical force. On a perfectly round vertical loop (360 degrees, and not tear drop shaped like most loops are) you are 6 G's its proven through physics.

Stitch Posted March 1, 2003 Share Posted March 1, 2003 The 360 degree or Sunshine loops are all ways made very larg to make the force bearable. Quote Link to comment Share on other sites More sharing options...
Scooby_Doo Posted March 1, 2003 Share Posted March 1, 2003 oooooh so thats why Vortex hurts my collar bone...and as for Delirium man that ride is gonna be WICKED!!!!! Quote Link to comment Share on other sites More sharing options...
Dane Posted March 1, 2003 Share Posted March 1, 2003 Thanks for the Physics lesson Shaggy! Thats funny because right now in my Physics class we are learning g's centrifical force, newtons, acceleration, speed, all the good stuff. Our book is littered with pictures of coasters, but no names. Quote Link to comment Share on other sites More sharing options...
Stitch Posted March 1, 2003 Share Posted March 1, 2003 Yeah my Science book has alot of Coasters in it but they are mainly Zyklons (Pepsi Python) Quote Link to comment Share on other sites More sharing options...
Scooby_Doo Posted March 1, 2003 Share Posted March 1, 2003 MAN! iam soooooo happy iam not in school anymore...all that homework it drives ya Insane!when i was in School we had the same thing expect my Teacher would teach about Physics by showin us Movies of Coasters!

Losing Streak Posted March 1, 2003 Share Posted March 1, 2003 Don't dare argue the OTSR- Horsecollar point on this board... Somebody will fight you to the death that they are different, when we all know that they're the same, some just have more padding and features. A car's a car, whether its a geo or a benz.

FOF Posted March 1, 2003 Share Posted March 1, 2003 OTSRs, and Horse collars are the same to me, they both go over my shoulders, but there is a slight deifference, which has to do with viewing. However the dicitonary on Coasterglobe says this, Horsecollar - A type of restraint that swivels down and over the shoulders. Not to be confused with an OTSR. OTSR - Acronym for Over The Shoulder Restraint. A type of restraint that comes vertically down over riders' shoulders. These allow for a better view than horsecollars. Call them wnat you want, but as far as im concerned teh 2 terms are interchangable. Quote Link to comment Share on other sites More sharing options...
Losing Streak Posted March 1, 2003 Share Posted March 1, 2003 Yes, and thats been my arguement, as long as i've been bob dole, or theataris, but somebody (I can't remember who) fought me forever about this, saying that they were not interchangeable. I have a few ideas, but i'm not going to just accuse anyone. Not out to offend, just to have a little fun. We will see if I am right, because the two people I am thinking of don't hesitate to post.

teenageninja Posted March 1, 2003 Share Posted March 1, 2003 I'll admit that was me Bob Dole, I am more lenient now though so I'm not going to fight on minor stuff like that. I think that Horse Collars give a better view than OTSR though. Quote Link to comment Share on other sites More sharing options...

matt3224 Posted March 3, 2003 Share Posted March 3, 2003 They have just finished the site....It looks so much better! They now have the new logo... I have to say it looks a lot better than before. Quote Link to comment Share on other sites More sharing options...
Losing Streak Posted March 4, 2003 Share Posted March 4, 2003 I like the design. Sadly, I think PKIU has a way better design, and much better content. I only say sadly because PKIU is essentially on a shoestring budget, and PKI has multimillions. But PKI.com is way better looking and feeling then ever before.
