There should be more funding for research like this

 

[Beauregard]

I love this; something I would totally do if I had the resources.

 

[BWells]

great laugh thanks for this!

That was awesome! Now, the question is why did the pickup truck tire go the farthest? I noticed that one of the tires (I forget which one) flexed quite a bit going up the ramp. I suspect that this flexing dissipated a lot of energy. I also suspect that the huge tire at the end would have won if the ramp didn't break.

I figured the big one would destroy the ramp. Reminded me of when I taught my fat friend to drop in and he broke the half pipe. And his leg.

Maybe that's why they told me that I was too fat for the louge track... hmm..

When it comes to louge, fat is horsepower.

Apparently, that's only true for the bobsled. Not true for louge and skeleton.

Largest diameter (tractor aside), probably stiffest vertical flex means that all of the energy was transferred up/forward off the ramp and not absorbed. I'm no physicist, but this is my guess.

heavier objects of roughly the same size almost always fly farther in these cases. tons more momentum at the bottom of the ramp + not much more air resistance = longer distance.

Eddie The Eagle Edwards can only wish to have been as good

So a short, fat dude would absolutely own at ski jump?

 

[Beauregard]

M.O.I.

Exactly what I was thinking.

ud get the same result if the object were sliding down the ramp (assuming a frictionless surface), i.e. not rotating.

So a short, fat dude would absolutely own at ski jump?

iono. i think theres a lot of skill and strength involved in the launch. plus, those skiers try to generate lift w/ their bodies and skis.

My pea brain tells me that the heavier truck tire won out because it was narrower than the touring and sport tires. Less friction with the ramp means less impedance with gravity.

Gravity doesn’t discriminate between fat or slim, rich or poor, black or white, old or young, gay or straight…
