 Poster: A snowHead
|
There have been a lot of questions lately about the right length of ski for a person.
It got me to thinking about my own skis. My skis are 167 in length, I am 6ft, 13st, and an advanced intermediate. Should there be a certain length of ski for me?
So is there a formula or rule of thumb for working out lengths? Or even a minimum/maximum length people should use for their height, wieght, ability etc?

The_Hirsty, Type of ski has a huge bearing. Piste only, go for good side cut and around nose height (however i prefer a GS style ski and ski 178/182 and am 176cmm tall.) All mountain, depends what you consider all mountain, but around forehead/head height.( i ski 177, but she is wide.) Off piste, well i ski 10cm over head height.(188cm)

How does a ski change its characteristics?
How much is due to the height of the object on top of it and how much to the weight?
If you put a ski on blocks - one at the front, one at the back, and stand on it, will it deflect more if you are 5ft and 10 stone, or if you are 6ft and 10 stone? Will it deflect more if you are 5 ft and 12 stone or 6ft and 10 stone?

standing still i would have thought that the weight is the factor but if turning on a ski would it not be a factoor of force * distance from pivot point so height is a factor???

Playing devil's advocate, in your scenario if the 5ft person leans forward and then the 6 foot person leans forward the ski will deflect more with the 6ft person because of the additional leaverage the extra height gives.
Does that not have a bearing?

ntfarmer, lower, good point, but how much higher is the CoG/CoM?
I don't know the answer, but I'd guess that the CoG of a person who is 6ft is not 1ft higher than that of a person who is 5ft

When the person is leaning forward, i'd expect the CofG to move quite a bit as your head is pretty heavy and is now 1ft further away from the ski. Not only that, your trunk is now ~6 inches further from the ski and that combined with you head i'd have thought would change the forces quite a bit.
However, if you are skiing with your centre of mass over the centre of the skis, it wouldn't make any real difference.
