400+ ft bike and snowmobile jump
Holy ****
1) How do the designers know the right takeoff and landing ramp designs?
2) How does aero work on bikes and snowmobiles so they stay upright and slightly nose up?

1) physics
2) it's not a matter of aerodynamics, but again physics. Namely newton's third law. But the throttle and the front will come up. But the brakes and the front wheel will come done. MXers have been doing it that way for decades to position the bike for the landing

They know the ramp exit angle, and the size of the jump, they have past data from smaller jumps to know how much it will slow in the air due to drag, and past that all they need is to calculate speed then the rider hits it at the exact right speed, not a guessed speed.
As for the nose, you just accelerate to lift it or brake to lower it. As the rear wheel accelerates in a forward spin it has an equal and opposite reaction on the rest of the bike rotating it backwards, and vice versa.

Engineers and designers are the unsung heroes behind the scenes.

With all the motorsports documentaries in Netflix...
Can anyone recommend one that shows behind-the-scenes of these stunts? (ramp design, testing, building...)

That's for another day, and another beer ðŸº
I love canada
EDIT: Pretty sure he uses lots of physics
Just gonna send it
