How rollercoasters affect your body - Brian D. Avery

View full lesson: ed.ted.com/lessons/how-roller...
In 1895, crowds flooded Coney Island to see America’s first-ever looping coaster: the Flip Flap Railway. But its thrilling flip caused cases of severe whiplash, neck injury and even ejections. Today, coasters can pull off far more exciting tricks and do it safely. Brian D. Avery investigates what rollercoasters are doing to your body and how they’ve managed to get scarier and safer at the same time.

I don’t think people realize how complex coasters are, I worked one at Cedar point and the control panel for it is huge with a million buttons and there is so much to rides people never realize that

[@demoniack81]

Do you guys have control over the force of the trim brakes around the track? I was at Mirabilandia this weekend and we rode Katun like a million times, including almost an hour nonstop before the park closed. It felt as though once the operators saw that the only people left were the ones getting off only to run back to the entrance, they turned the trim brakes way down. We harldy slowed at all at the trim brakes and the final brake run before the station almost pulled my face off a few times. (edit: not that I'm complaining 😂)

[@charliew1822]

So the control panel is only the tip of the iceberg as far as just the control aspect of a ride goes. The PLC cabinets are a mess of complex systems. Trims on rides cannot be manually controlled on anything more recent that 1990. They are usually set to apply various amounts of braking force based on the speed of the train, which moves slower when lighter. So if you were the only few people on the ride, the train was probably running slow enough to not need to be trimmed by the system

Don't be scared of riding rollercoaster, I've ridden a lot of them (from small children's rides, to coasters with 14 inversions). In Western countries and Japan, there are so many safety measures, and the laws are were scrict. 2 people die in a rollercoaster accident a year (worldwide, including China), sound crazy huh? Well this number translate into: the chance of dying on a coasters is 1:600000, that safer than flying, walking down strairs and driving a car. Six Flags coasters aren't dangerous, but a lot of them can use a new coat of paint! Bottom line: don't be so scared, it's way safer than you might assume!

@@nathaniel9526 it's all depending on how your body handles the g-forces. For most enthusiasts, they are quite fine since they know how to breathe properly when riding. If it's someone who strongly fears roller coasters and is breathing heavily or panicked, they will likely pass out. But most of the time, people are fine and it's very rare for someone to grey out or even pass out.

(Airtime hill) and now you're going trough another turn that gradually increases in height and lowers in a time of around 8 seconds. now you're heading towards another high off the ground turn (overbank) and you come back down and enter a 20 degree turn. Now you're going over a smaller hill, and you feel, once again, weightless. Now, you enter another tunnel which also has a turn, which takes three seconds, and now you're going over a really small hill that makes you fly up against the safety restraint, preventing you from being launched out of your seat. now you enter a 35 degree Turn that takes around 2 seconds, and then you go straight for a very short time, then you enter another turn that's pretty high off the ground (Overbank) and you go back down. You start to go slower in a short period of time. now, you enter another very small turn and slow down even further. then you go straight and you roll into the loading station, the place where you got in. now your safety bar infront of you opens, and you step out and exit to the left side. _and yes, I did just describe the entire ride experience on Millenium force_ kzbin.info/www/bejne/f4qxp5-cdtufrNU

Interesting. Most recent rollercoaster I was on was the VelociCoaster in Universal Orlando. My favorite types of rollercoasters are the ones that are either really fast/strong acceleration or have drops. I don't really care about loops, they don't do much for me. The VelociCoaster wasn't very scary, but it was really fast and I was really glad they made us leave everything in the lockers (cellphones included), because I'm sure everything would've flown out otherwise. I was actually really busy holding onto my hair during the ride (I had my hair in a bun because it was hot and it was uncoiling during the ride. I should've just worn a ponytail). Hearing the guys next to me scream and swear was quite fun.
