Engineer Explains Every Roller Coaster For Every Thrill | A World of Difference | WIRED

In this edition of "A World of Difference," Korey Kiepert, owner and engineer with The Gravity Group, goes through the 8 main types of roller coasters and breaks down how they work as well as the decisions behind why they get built in the first place. Korey explains the difference between a giga coaster and a strata coaster, as well as what separates a "wild mouse" from a "mine train."

  • The graphical representation of G-forces happening while the car is going downhill, that's not accurate. The whole time I was waiting for the car to hit the bottom and suddenly level out. -That- would be when you get G-forces. Otherwise, they're not feeling much - it's freefall.

  • 18:00 - Not to come off as pedantic, but the X2 coaster is not a free-spinning 4d coaster. It’s a distinction worth mentioning because one of the reasons X2 is so buttery smooth (and one of my favorite coasters), is because the rotations of the seats are specifically dictated by the portion of the track you’re currently on- there’s no randomness. The result is a smooth ride designed around your center of mass, which means less of that disorienting and painful whiplashed feeling. I make this correction with ZERO disrespect to the engineer here. He’s obviously very knowledgeable and knows his stuff and knows WAY more about coasters than I do! Just thought this one note was worth mentioning. This was a great video! Entertaining and educational! The best combination of things!

    Keto WolfKeto WolfMåned siden
    • I said the same thing in a different post. X2 and Eejanaika control the rotation. All other 4D do not have the 2nd set of rails and actually are free spinning.

  • I went to a very large amusement park with some friends and when we were walking over to their newest coaster, which had an inverted section, there were a bunch of park people and medical people blocking the way so we walked around the crowd, looked up, and saw that the coaster had stopped right where the car gets inverted, so about 30-40 people were trapped upside down for what must have been 80-90 minutes. I learned later that there may have been some pretty serious medical problems due to being upside down for so long, but idk what happened to those people, they were only just getting moving when we were leaving. Absolutely killed MY excitement, though, and really, that’s all that matters.
