  1. Pretty sure its not vertical at that bit yet. Which i why I said: So I maintain what i said earlier that when the car clears the curve and is running on the purely vertical part, the load on the track and tower is quite low, since the only real forces are the odds and sodds like crosswinds or unbalanced loading. Its nowhere near 7.5 tonnes, or 6 tonnes, its probably lucky to be half a tonne.
  2. Yeah I was clearly talking about the vertical section, not the directional change. Clearly when the track curves and peels away from the tower you hit 4.5g, that's why there's a particularly chonky support Backpedaling/ contradictory posts:
  3. Another way to consider it is the other vertical track on that tower... Giant drop. Say the gondola weighs four tons. On the way up what is supporting that four tons? The track or the winch? What the gondola is released? How much is the track supporting then? Likely only a small amount sufficient to keep the gondola falling straight, enough to resist the wind Blowing it off course or uneven seat loading making the thing tip.
  4. So yes I should clarify, there's probably a bit of force against the track, eg if the car is rear loaded it will want to tip forwards etc so, upstops are necessary. But by definition it cannot be the "full 6 tonnes" as you claim. Remember the 3rd law. Parked in the station the car exerts 6 tonnes downwards. The track exterts 6 tonnes upwards in return. If it didn't, the track would collapse and the car would land in the gift shop. When the car heads up the incline to vertical, that is what gets the tower shaking. It goes from pushing down through the columns to ground to transferring against the horizontal ones that were braced against the tower as it curves up Now the vertical part ... The track is able to guide the car "a bit" but is mostly not supporting it. The car would not be able free fall at the speed of gravity if the track was applying a significant force to prevent that. The track that was preventing the car from falling through the station floor is now doing nothing to prevent it falling vertically. That's why shallow drops like on roadrunner pick up speed slowly but vertical ones accelerate down at near the full 9.8ms² Again, you're ignoring all these other examples where coasters with vertical track slim down the structure in those parts. How do they get away with it @New display name?
  5. But the weight of an object is just the force acting on the mass of an object due to an acceleration (g force) or gravity. No gravity or force, no weight. The mass is constant, the weight of the object isnt. Think of this way. If the ride isn't running, there's no load on that bit of the track. If youve got a car coasting down the vertical track, there's no meaningful way for that car to put load on the track, it's "falling past it", so its not really putting any major load either. It might as well not be there. Imagine instead of a coaster it was a filing cabinet and a glass of water. If you put it on top, the glass is putting full force on the top. If it slips down the edge, its putting minimal force on the cabinet as it skids down the side. Here's another example.
  6. Only when it hits the curve. Only by a small amount. And think about what you are saying. When you are at rest your butt is putting your weight x 1g on the seat. When you are on the curve you are putting your weight X 4.5g on the seat. When you are on the the vertical you are putting almost no weight on the seat because you are floating out of it. So therefore it follows. -When the car is in the station its 10 tonnes on the track (or whatever) -When it is on the curve to vertical it is putting 45 tonnes on the track. -When it is coasting vertically, its putting almost nothing on the track. A really good example of the physics of this in action is on an impulse coaster. Notice how the curve to vertical has quite heavy tube supports and a cluster of track connectors. This is the highest g load section of the ride, as it swoops under the trains are really pulling down on the track. But when it gets to the vertical part, there are minimal extra supports. Why? Because at this point the train is coasting up / falling parallel to the direction of the rails/ its not pushing down on the track, its "rolling with it", so the track is practically self supporting. And then in the station its lightweight supports again because even though its going at high speed, its still only pulling down 1g Another example would be on dive coasters. The track ties are further apart on the vertical part because the load is minimal, and then get close together again on curve at the bottom when the Gs hit. Compare the distance between supports normally versus on the vertical part: But yeah Slick is right, there would be a little bit of force on the car, eg wind blowing it sideways that would try to 'twist' the track, the car being unbalanced and wanting to shear a bit, but not a whole lot.
  7. Wouldnt the TOT car have put basically neglible loads on the track at that point, since the car is effectively weightless for the entire vertical section. Its not pushing down on the track. Not saying that the tower would fall over, just that its more re-engineering. FWIW having sail type letters would be less visible to southbound traffic IMO, since the tower itself is hiding them till the last minute. Perforated steel I've got no issue with though. From a distance you cant tell.
  8. Yeah in the wind I think the letters would be like a sail, and pull a bit on the old track connection points in a direction not originally designed for.
  9. Don't be like me and stare at this for 5 minutes Trying to work out where the D is in Tower of Terror
  10. @DaptoFunlandGuy go to SW San Diego instead, they have that new dive coaster and a new jet ski coaster opening this year too.
  11. Random question for flat ride thoosies, how do you tell the difference between a Zierer one versus a P&B one? I mean with coasters you can tell the difference between a good and bad manufacturer because the good ones are smoother and have better shaped elements. But is this the case for a simple spinning flat ride like this? What's the point of difference.
  12. @DaptoFunlandGuy there are definitely better parks than Knotts anyway.
  13. To me its no different to Universal Wonderland at USJ where you have Snoopy, Hello Kitty, Sesame St in the one zone.
  14. I thought the two adult flat rides were Batwing and Doomsday. Then again I'm confused as to why kids coasters count to make the 9 but kids rides don't count.
  15. I'm confused, how do you mean they didn't announce an opening date? Wouldn't the opening date just be the day after the end of the maintenance period? Eg with Serpent Slayer, the maintenance period ends 24th of March therefore opening date is the 25th of March. Am I missing something here or am I some kind of genius?
  16. Put the facades on the back of the Justice League building As for colours, could you do red supports blue track instead?
  17. Yeah but you cant just make the theming shit to achieve that 😆
  18. They still have an animation showing the seatbelts and a safety spiel when dispatching so its fair lol. ********** But lets be honest, if they had opened the ride and had put safety footage on the underwater screens you probably would have said it was crap and spoiling the immersion. Safety videos are ok on smaller screens approaching a station. But not on screens and projections that are being used for atmosphere and theming. Note, both of these examples are from Sweden.
  19. Ok but I think with Hagrids its themed like a motorbike workshop, with random diagrams and repair manuals for motorbikes, with some animated graphics (As is the case with books and posters in the HP universe) so you can make it suit the theme and its not a major screen. The irregular, cavelike screens in the Levi station just dont lend themselves to schematic graphics showing how to board the train and it would break the immersion too much. It's the wrong screen to use. For example on Rise of the resistance: they dont even try and put safety into on the big screen in the hangar bay They dont put the safety info on the screen with kylo ren (even though you are locked in that room with nothing do to) Instead they do it on a smaller screen where it makes sense. The type of screen that looks like is used for showing status of the ship system, so it doesnt look out of place to show a seatbelt in the car as part of that system. @Dean Barnett when making suggestions like this, you need to think about WHY they would have done it in a certain way or in a certain place on another attraction, not just the fact they did it in the first place in general.
  20. What makes it a 0% chance of something happening though?
  21. I always thought the best comparison was Green Lantern Versus Abyss: For what its worth, this is probably the best i could come up with: DCR vs Leviathan – High Tier Coasters SE vs ST – Large Launches MCMC vs JR – Straddle Coasters GC vs Big Dipper – In effect comparing the old with its replacement (In the day you probably would have done GC vs Arkham or GC vs Sea Viper) Scenic Railway vs Wild Mouse – Wooden Classics Surfrider vs Project Zero – Compact shuttles Bug Run vs Little nipper – Small Family Coasters Sapphire speedster vs Mining Race Coaster – Medium Family Coasters Boomerang vs Road Runner – Larger Family Coasters Speedy Beetle Vs Crazy Coaster - SBFs TNT vs Escape From Madagascar – SFCs Dragon Express Vs Boating School Blast – Zamperla ST80 Abyss Vs Green Lantern – 8 seaters, Beyond Vertical Scooby vs Dingo Racer – Steel Mice, but a poor comparison. Still leaves Storm and the thing at Green Valley Farm unaccounted for.
  22. So what about Anaconda / Dragon Mountain / Tennessee Tornado?
