If you go the ideal physics/trig route it should be easier than that:
#G's = 1/cos(angle) where the angle is how far over your center of gravity is leaned (not how far the board is leaned), where 0 is straight up and 90 is flat on the ground.
Standing straight up, 1/cos(0) = 1 G
Leaning over 45 degrees, 1/cos(45) = 1.41 Gs
Leaning over 60 degrees, 1/cos(60) = 2 Gs
3 Gs would be leaned over ~70 degrees.
Although you can get the board almost 90 degrees over, I doubt you can actually get your center of gravity much further over than 70 degrees.
but in reality it doesn't really work out that way; both Jack's and my formula's ignore the slope of the run itself (fewer G's at the start of the turn and more at the end), the fact that carving is dyanamic, and you are not really ever at equilibrium so the forces don't actually have to sum to 0, etc..
Looking at all this info, i think it would be safe to say the doing some leg training at the gym is going to greatly improve your carving skills. Most of us probably cheat and straighten our legs out, and that is basically taking away your suspension.

Let's say 15m board at 60 degrees, 200lb rider...
from the math here, that would be
turn radius - 7.4m
speed - 11.3m/s (about 25mph)
= 1570.24 Newtons of centripetal force
divide by mass (91kg), divide by g (9.8) = 1.76 Gs.
nice man, figured out the g's from the angle.....I don't think we know the turn radius or the speed though.
-
How do you derive 3 Gs from that picture?
just a guess...I think I read somewhere that alpine carving can reach 3g's, and if there's anybody who can reach that, I'd assume it's that guy, in the middle of a race no less.
-
Err..600?
well you can't count your own body weight, because when you squat 300 pounds, you dont count yourself. Also you are not squating your full body weight in a 3g turn, you cannot count your leg below your knee, and only about half of your leg above your knee, so you have to subtract that weight. I'd say a proper squat at 300lbs is about right.
-
You might see it better in everyone's favourite Jasey-Jay action shot. I don't think anyone here is driving their back knee any harder than he is, and it's nowhere near the board.
wow if that's the proper position for carving, I need to get to the gym. If I'm pulling a 3g turn and I'm 200 pounds that means I'd need to squat atleast 300, and I can't lol.
-
anybody know what the conditions are like there at the moment?
-
definatly shine them up and hang them somewhere in your house, maybe if you have a game room or something
-
to the OP - what is the battery life of those bluetooth headphones in sub-20 degree temps?
(That has been an issue with a lot of the rechargable devices I have used in the last couple of years)
It gets me from lift open and usually dies on the last run
It usually last longer then the device that is playing the music.
-
anybody have a pic? or a link to a thread with a pic?
You would be expanding your potential buyers by informing us bomber online rookies of what you are selling
-
I haven't seen any pictures
you certainly seem confident this is going to be the hot ticket, what is it?
-
I wasn't trying to start an arguement, many people on the forum use them. If you do, make sure you check these out. If you don't, don't check them out :shrug:
-
IMO it's perfectly safe listening at a moderate volume, they are not over the ear headphones that block out the world.
IMO I think it's perfectly fine for an advanced rider to be able to listen to music on the run. I think it's pretty instinctive for most of us to know where everybody is at all times.
-
I'm sorry, headphones have no place at a ski area. Without a sense of hearing you are a hazard on the trail. At least the dolts that ride with earbubs you can see the wires to their ears and know to stay clear of them. But wireless bluetooth ons that can hide under a helmet and hood are just a bad thing.
thanks trail police, I guess I'm a menace to the slopes.
You can usually hear what you need to. The headphones do not over power someone yelling or skidding out of control.
-
Just letting you guys know what I use for the slopes.
They are stereo bluetooth headphones, Iphones and ipods are not stereo bluetooth so they won't work with those peticular mp3 players.
These are what I use, the motorola s9, they work only with cell phones that are stereo bluetooth. They are completely wireless and you can control the tracks/play/pause/volume from the headset. If somebody calls you it will stop the music and you can answer the phone right from the headset
These just save so much hassle for me with no wires and they sound pretty good for being wireless. I can have them on for an entire day under my gear and they are very comfortable. At a full charge, they will pretty much get me from lift open until lift close, and pretty much die on the last run at full volume.
this is how you wear them, so they don't really get in the way of your gear
No I don't work for motorola lol, I just love them so much I'd figure I'd share them with you guys.
-
I've never seen a board like that on the slopes
might as well throw some bindings on a ski
-
just found this, anybody ever try it or hear anything about it?http://cozywinters.com/psolar/facemask-balaclava.html?source=go&gclid=CNj_3vGl7JgCFQVuswodPkyy0g
-
I'll use one sometimes.
They're actually colder than a regular helmet because the mouthguard won't let you pull up your collar.
so you had issue's covering your chin/neck with the full helmet?
-
That's what I use now, honestly they do keep me warm, but I loathe the wet face mask. It always soaks up moisture from your breath and gets wet. I have to dry it out atleast once a day. I was hoping a helmet would just keep your entire head dry and warm, problem free.
-
hmm, I like those, thanks for the link. I'm mostly concerned about comfort, but it looks like those helmets are set to some sort of european standard, so I'll assume they have decent amount of protection.
what do you guys use for extremely cold weather comfort?
-
Looking for experience from people that have used them.
I was just wondering how warm they are. On days that are windy and below freezing, the old goggles/knit cap/and face protector combo doesn't work too well. It gets moist from my breath and freezes within a couple hours.
I was wondering if a full face helmet solves this issue. Honestly what I'd really like is a full face motorcycle helmet, that basically gives your head its own atmosphere, but that would look sort of goofy on the slope.
To people that have worn full face helmets while riding/skiing, are they nice and warm? I guess you just need a set of goggles.
I just can't stand riding on the lift with 40mph gusts at a -20 wind chill.
what do you guys use to make riding in extremely cold conditions comfortable?

i'm typing this thread while on my way to Stowe for 4 days and was hoping that someone may know if there are any shops near Stowe that carry Alpine / Carving equiptment...?
Thanks,
Marc
I called almost everywhere in VT including up north, the starting gate seemed to be the only place that actually had something.
Stratton is pretty far from stowe
-
thanks for the offer, but I have found a pair of boots and am awaiting their arriving.
-
please respond....I'm dying to get out there while there is still snow left this season, I have my board all setup staring at me everyday, I just need boots.
I'm interested in the burton reactors

Hey all,
I'm a long time skier (12 years on skis - 170s/skiboards - 110s) who is looking for a new approach to carving up the slopes. I've always loved carving more than any other slopeside activity, even on my skiboards, and I think it's time for me to move on to alpine snowboarding. To give some quick background, I'm 5'8 and 130lbs. I've only snowboarded one season before, but it was on soft boots and nothing really became of it. I need a full loadout of gear to get myself started and learning - I'd really like to get started this season if I can!
As far as the board goes, I know that most sites, carver's almanac included, say that the best beginning board is all-mountain, but I think I'd prefer a more carving specialized board like a freecarve board or maybe a damp race board. Would I be fine learning on these types of boards or would it be impossible? Do you guys have any suggestions for specific board lengths/models that would suit me best? Ideally, I'd like to get one board and keep it for as long as I can, so I'd prefer getting a board I won't grow out of.
As far as boots - my ski boot size is a mondo 27 solomon performa 6. I also have a pair of nordica boots which are 27.5 which fit me fine - both sizes would work for me. I know everyone recommends buying boots new, but is there any place I could get new boots for less than $500? Money isn't a gigantic issue, but I'd rather be economical if I can. Are custom footbeds/heat moldable liners all that important? Again, I'd rather buy all the intermediate-advanced gear now as long as I can learn on it so as to avoid spending more money in the future, so I'd rather buy the custom footbeds and liners if they are going to make a huge difference when I'm more proficient. Any specific boots/shells that you guys could recommend? I know I could always buy the liners separately.
My understanding is that with my weight, the bindings aren't really all that important - does anyone have a set of cheap burton race plates or perhaps bomber TD1s? The same ideology behind not buying beginner-only gear applies here as well.
Thanks a lot for all your help, I really can't wait to get all my gear and get on the slopes!
where do you go? poconos or VT?
I'm from Jersey as well, right outside of philly (cherry hill area), I just bought a bindings and a board and am looking for boots
Wouldn't mind learning with somebody else if you're interested. Maybe day trip to poconos... I have a place in VT but that's kind of a hike.
