7/24/2023 0 Comments Negative g force on mako![]() This is all conjecture, because I don't work for B&M, but this is the basic essence of engineering. It's probably worth also saying that B&M probably try to aim on the faster side than slower, as it's easier to trim speed off than it is to boost it. People with lots of laps on specific B&M hypers (or even comparing different people's experiences of the same ride) will be able to speak to this well. Conversely, on a cold day with a partially empty train you may find all the hills feel very lacklustre because the train is running slowly. So if you're in the front row on a hot day and the train enters the hill 5% faster than B&M's "perfect" speed, then you'll probably get a little pop of ejector as the train begins to crest the hill. If they can get between +0.5G and -0.5G across a hill in their 'worst case' scenarios, they can be reasonably sure that in the real world the coaster will always land somewhere in that bracket. They'll make sure their coaster will still work (and be comfortable/safe) with an empty train on a cold day and a full train on a hot day and probably a few other 'extremes' to build an area of tolerance into their model. Of course, B&M can't control most of those factors, so there will always be some variation in those parameters in real life.ī&M will probably run a series of scenarios, considering first the "ideal" then testing that solution against a range of scenarios where they tweak some of those inputs. This train is likely modelled as some point at the centre of gravity of the train, likely with an ideal weight, rider distribution, wind direction, air resistance, etc. However, what they're actually doing is calculating the path for a 'perfect' coaster train. ![]() And yes, in theory that would mean you wouldn't see riders being pushed against the restraint. Yes, in theory when B&M design their parabolic hills they calculate the curve for the 'perfect' zero-g experience. I think there's some important things to consider which, whilst your A-level physics isn't wrong, is stuff where "physics" becomes "engineering". ![]() So my basic question is do B&M hyper coasters actually produce any negative g-force, or “actual airtime”, if you like? Are my theories based on what I know from A Level Physics correct, or is there more to it?ĮDIT: Whoops, just realised I posted this in Polls as opposed to the Q&A section like I meant to sorry! Could a mod please move this thread to Q&A, if they wouldn’t mind? Further to this point, I’ve also heard some sources say that rides like Mako and Shambhala go right up to -1G at parts of their layouts, and I wouldn’t be too surprised if a ride like Fury 325 goes well below 0G in that ending section. From the Physics knowledge I have, I’d guess that 0G is more of a sensation produced by the lack of gravitational forces, and 0G in itself cannot actually push a rider up out of their seat, so surely these rides must have negative g-forces if the riders can actually been seen coming up out of their seats in ridercam videos? With gravity acting downwards, a negative g-force surely needs to act for you to fly upwards, no? Also, from anecdotal experience, I’d say that the airtime on Mako, the one B&M hyper I’ve done, felt equally as strong as, if not stronger than, the airtime on rides like Icon, which is said by Blackpool Pleasure Beach to exert -1.2G. However, I’ll admit that this notion confused me somewhat whenever I watched a ridercam video of people on a B&M hyper coaster, because when the train passes over the first drop or the parabolic hills in those videos, the riders seem to fly out of their seats as though an actual g-force is pushing them up out of their seat. Further to this point, I’ve heard from numerous people that B&M hypers are designed to exert a perfect 0G over their hills, so in that sense, many argue that they don’t have any actual “airtime”, as no forces supposedly act to push the rider out of their seat. When reading through threads about B&M hypers, one of the most common things you hear about them is that they focus almost primarily on floater airtime as opposed to ejector airtime. I’ll admit that this has always confused me, as I’ve heard and seen differing things that offer different answers to this question. But on the subject of airtime, I have a question about B&M hypers do they actually produce any negative g-forces? B&M hypers are an incredibly popular coaster type among parks across the world, and for some, they are among the ride types you think of when you think “airtime machine”.
