Zambroski Posted November 5, 2021 Share Posted November 5, 2021 I wonder what gearing he is using. Also, by turning all the outside "lugs" slightly outward, he should be able to gain more traction by getting rid of excess snow build up. Change my mind.

teamgreen02 Posted November 5, 2021 Share Posted November 5, 2021 What's the velocity of the lug tip compared to the track surface as it goes around the drivers, front idler wheels, and rear idler wheels? Quote Link to comment Share on other sites More sharing options...
Platinum Contributing Member Highmark Posted November 5, 2021 Platinum Contributing Member Share Posted November 5, 2021 (edited) One of the earliest (and coolest) sled video's I had (VCR of course) had some great video of guys who basically made their own mountain sleds and had bolted on track paddles similar to these but all the way across. Well before the Summit actually came out. The slow motion video matched to the sleds jumping in spring mountain snow was paired with great music. It was really awesome. Wish I knew what video that was. Pretty sure they long-tracked and put plastic paddles on these two sleds.

For a track there are many values of v (velocity) on the non-linear sections and the velocity depends on the contact point chosen. With anything there is the theoretical and the practical impact of the variable impacting the results. Most engineering problems are simplified to make the calculations easy and straight forward. +/- 10% of actual results is a good model.
