If you’ve ever been on a modern looping roller coaster, you’ve probably experienced a thrilling, safe, and mostly comfortable ride. But this wasn’t always the case. Just over 100 years ago, loop-the-loops were painful, not sturdy, and much more dangerous than they are today.
Between the 1840s and early 1900s, loops on roller coasters were perfectly circular - meaning riders would go from traveling in a fairly straight line to immediately moving into a curve. This rapid onset of curvature caused extreme G force spikes that rattled passengers to their core.
The first looping roller coaster in North America - Coney Island’s Flip-Flap Railway - could exert up to 14 G's on a person. For reference, astronauts in a spaceship launch experience 3 G’s. Fighter pilots with very special equipment and training can handle 10 G’s for short periods of time. 14 G’s was (and still is) tremendous.
More people paid to watch others ride these early coasters rather than ride themselves. Without sustained success, most looping coasters closed down within their first decade of operation.
Looping coasters wouldn’t find success again until the 1970s with a new loop shape, new materials, many more cars - and, thankfully, fewer G’s. In this video, we break down all the advancements that helped make looping coasters the popular ride they are today.

@Nova3674 2 года назад

As someone who studied engineering, works in theme park design, and is just an all around coaster enthusiast, can confirm this video is on point. Even using the the correct geometry based terminology of clothoid loops to describe the “teardrop” loop., made famous by the manufacturer Arrow Dynamics (who also helped make the Matterhorn). Fun thing to notice, Arrow built a number of geometry based coasters (as opposed to force-based) with the clothoid loop. But for a long time only used one size for the loops design. So the bigger the first drop, the higher the same sized loop had to be off the ground. Examples, Great American Scream Machine, or the still operating Viper at Six Flags Magic Mountain.

@alexz5620 2 года назад

For a similar reason train tracks and street curves (like offramps) aren't perfect circle sections like you may find on a model railway either. If they were, turns would be really violent or require you to turn your wheel in an instant.

@tristiancapozzi1194 2 года назад

Exactly, instead of semicircles they use segments of a spiral arc to make the turns smoother

@josephfisher426 2 года назад

It isn't that the circular section is "violent," but that it starts and ends too smoothly, and drivers' reaction delay leads them to go past the point where they should start turning noticeably. Making an unnaturally abrupt start to the curve (which is often how the curve is altered) forces the driver to start the curve sooner. With roads, which are much wider than most of the vehicles traveling on them, this is also an adjustment to the better drivers who will turn sooner on their own and run on the shoulder if you don't give them more space on the inside of the curve. With roller coasters it's different because there can be no deviations.

@CombraStudios 2 года назад

Yea transition tracks increase the centripetal force gradually and not immediately

@murdo_mck 2 года назад

Partly similar but in a rollercoaster the speed drops predictably as the car goes up then increases as it goes down which is why the bend radius is much smaller at the top. At 5:13 it's clear the G force is nearly constant.

@mightyjerseys93 2 года назад

@Justin.Franks 2 года назад

Sooperdooperlooper's loop is still quite a bit more circular than the loops on newer coasters. You can definitely feel more force in the loop than you would expect given the fairly paltry 45 mph speed. It's actually pretty surprising since the first drop is so gentle (as is the rest of the ride). It is cool though having the track pass through the interior of the loop. More coasters should do this, especially since coaster loops have gotten so much bigger with a lot more space inside. Maybe even put it towards the end of the layout after the mid-course brake run, so there's a chance your train passes through the loop as the next one is traversing the loop.

Spin a ball on a string in your hand and just sense the forces you feel in your hand. Then try to make a Smith circular spin straight after starting and try make a Smith sensible exit mimicking the shapes of these loops. You will see the circular spin exerts more pressure on you and is much more tricky to complete in a perfect circle as it naturally wants to break up the shape. It also shows that a less circular path exerts less pressure on the Shape as a whole meaning that structural integrity is safer not only due to material but the trajectory it's self

@wendyweaver8749 2 года назад

dfrocha1 - Simple estimated conversion of feet to meters: There are 39 inches in a meter, 12 inches in a foot and 3 feet to one yard. I.e., there are 3+ feet/1+ yards to a meter. So, 150 feet = 50 yards = 50 meters less 8% = ~46 meters (yards x 92% OR feet x 92% divided by 3). [To simplify further for head calculations: convert feet to yards (feet divided by 3), times 90% then add 2%.] Once you have done this a few times, you should find it quite quick to calculate a rough estimate. Being in the U.S., I use the reverse for rough estimates: 1.08 times meters = yards then times 3 for feet. Or use meter plus 3 inches per meter. This means 16 meters equals 16 yards + one foot per four meters = 17 yards and one foot. [To simplify further for head calculations: Use 1.10 times meters then subtract 2%.]

I loved riding the Laser Loop when it was in Kennywood Park here in Pittsburgh. The ride was sold and taken out in the mid early to mid 90’s.

@ltpenniss6691 2 года назад

I rode it many times before joining the Navy. The Laser Loop was powered by an old steam catapult from the USS Lexington aircraft carrier, that oddly enough I got to ride in 1987 for a "CQ demo" out of Ft Lauderdale while in VA-37 stationed at NAS Cecil Field. GO BULLS !!..

@medexamtoolsdotcom 2 года назад

Did the first one actually subject the passengers to 14 g's? Or was that just AN example of a circular loop and not a model of one that was actually put into practice? Because 14 g's is a lot. The hypothetical euthanasia coaster would only be about 10 g's but it would keep it up for a minute. Never mind the acceleration function being discontinuous, just it being 14 is a problem.

@danielking6426 2 года назад

It was also troubling that it was suggested that circular coaster riders were subject to an instantaneous jump from one to fourteen g’s. That is not possible. It could be very dramatic change - but not instant.

Man, seeing people use apostrophes to make plurals (it should either be Gs or "G"s) makes my eye twitch.

@philb5593 2 года назад

There's something off about those graphs. No way it is 14 g. The graph shows the modern coaster at 9 g, which also wrong. Halve those numbers and you're on the money. A circle would be more like 7 g and a modern loop 4.5 g.

@lawrencesmeaton6930 2 года назад

The same rules apply to roads! You'll never find a circular turn, for example, on a motorway or highspeed road, the change in gradient is just impossible to steer into. Instead, curves are made up of a series of parabolas which feel circular, but are not. If turns were circular, you would have to turn your steering wheel from 12 o'clock to the angle of the turn in an instant. But we all know that's not how you take a motorway curve, you slowly adjust your steering as you go round the bend, with your wheel turned the furthest at the apex, and then you slowly return it to the 12 o'clock position as the road straightens out.

There is a small problem that yall forgot which is that the flip flap railway and loop de loop needed circular loops to complete the loop without passengers and cars falling off the track and crashing into the bottom of the loop because they didn't have upstop wheels.

@Robbedem 2 года назад

You mean they needed enough speed and thus high g-forces to create enough centrifugal force. The loops would still have been better with the cochloid shape.

@comenting3207 2 года назад

@@Robbedem Exactly but they didnt think clothoid loops because in the 1800s to early 1900s safety was the second priorty

@maxhagenauer24 2 года назад

I don't actually know if they had upstop wheel back then but if not, you still get a little under 12 Gs on the top of the loop when you only need 1 G to keep it up so it doesn't fall.

@SmallSpoonBrigade 2 года назад

Yep, this is why when you're engineering something like that, you'd likely want to go with a shape that keeps acceleration to a tolerable level and adjusts the radius to make that work.

@emmarainbow9557 2 года назад

Even action park only had it open for one season! It was about 10g. People were consistently hurt by it, so they added padding. Then people were cut by it. They investigated and they found previous riders had left teeth embedded in the padding.
