TOPIC: Shape of ski under load?

  • Today is a gift, so ski. No promise of more.
Have you ever wondered how much a ski flexes under full load or in a turn?

When we flex test a ski, we flex it only one tenth of an inch. That might only be the thickens of a half dollar. Of course it depends on the stiffness of different skis, but it might take 100 to 150 pounds or so to flex the mid section that one tenth.

Keep in mind, during the test, the ski is supported 24 inches apart and being pressed on in just one spot half way between. However, when we are skiing, we are pressing on one side of the ski with two big feet, dispersing the load on a large area, and the water is pressing back on an even greater area.

What are your thoughts?

Yes, some pictures do show a fair amount of flex which occurs mostly between the rear binding and tail of the ski. Not only how much flex but how many flex cycles does a ski have in its useful life.
