that guy has some serious issues.
-
Thats just sad
-
wow, that must have hurt both person and bike x.x
-
Poor Bike. The person deserved what he got for stupidity
-
Woah that was freakin stupid O_O
-
ouch...
-
I feel horrible I'm actually thinking of ways to make it work
-
At least my respect is no longer 13 now :P
-
*downrate*
:P jk
I don't know how that would work...looks like it could go on AFV tho
-
They must've had to mount that ramp on the truck pretty securely, or Bernoulli's Principle would make it act like an airplane wing and lift it up.
-
Heh, if they had brought their calculators they could've obtained the correct speed to be traveling at to make it work. :P

I think that because it's a concave surface it would actually create a downward force. Or I could just be crazy. :P I think that the surface would create an increase in pressure, thus slowing the air.
-
It is still a slope, the air would still be moving up it, though at an increasingly slower speed.
-
Bernoulli's Principle when dealing with lift requires that the speed be higher on top rather than on the bottom as is the case here. Basically, in a sense, reverse-Bernoulli's Principle. :P
-
No, the bottom of the ramp is flat, so the air there stays still for the most part, with the bottom of the ramp just moving over it, while the air has to move up and over on top of the ramp. Though I still don't get how stunt planes can fly upside down, wouldn't a reverse-Bernoulli effect occur, pushing the plane down?

I've never understood this either. COuld someone please explain how planes fly if they can also fly upside down so the wing idea doesn't work

The shape of the wing cross section is such that lift is created by the angle of the on coming air on the wing. So roll over and establish the same angle and you get the same upward lift because aerobatic airplanes have some what of a symmetrical airfoil shape.
-
They'll just need to angle upward a bit.

Ouch x.x, some people really love to take risks...

Reminds me of an xkcd comic. I'll try to find it...

[tangent]I wonder what would happen if that ramp'd truck started driving the wrong way on the highway ;D

It was the same comic I was thinking of :)
the tangent would be pure evil

Don't need a ramp, just need to find a bulldozer that has that same sort of slope. :P
But the van could prolly go faster...
-
It'd be kind of hard to do that "trick" on a bulldozer though, as the very bottom of the scoop is usually not parallel to the ground like the ramp is, resulting in an angle between the road and the scoop and not a smooth transition like the one on the van.
Also, for anyone who is interested, I looked stuff up and figured out how planes can fly upside down. They are tilted pointing up (while upside down, from and observer's perspective) that the leading edge is higher than the trailing edge, which generates lift, though inefficiently compared to an airfoil.

Yay I can finally understand it

That is an unbelievably stupid idea. That must have hurt.

He'll probably never be able to have kids... I wonder how long he was in the hospital?
