Stupid Questions

[devilof76]

Only if you're in the air long enough. When you jump you're going as fast as the train. In the air, you'll be maintaining that speed for an undetermined length of time. If you're feet are back on the ground before that time elapses, then no, you won't land further back.

How do I get an infraction on this board?

Practice.

Aerodynamically speaking if i'm standing upright the windforce will reduce my speed while train continues at the same pace

Like when parachuting you'll fall fast with your arms tucked, body straight and head facing the earth than with the earth facing yous torso and your arms and legs extended out

I just can't wrap my brain around being able to stand on a train going 300mph without any means of support other than body weight, or in the air, without being blown back to the rapid wind pressure

What keeps you in a stable position isn't your body weight, but the force of friction between your feet and the surface of the train. Also, by Newton's third law of motion, "every action will have an equal and opposite reaction". As the hypothetical train is traveling at 300 mph, it's also traveling through the air. And if you're situated on top of the train, you'll experience a wind force of 300 mph that is equal and opposite to the direction of the train.

The easy answer is, that you'll be blown off. Those are hurricane force winds.

If i'm standing on the roof of a train that goes upto 300mph i'll be pushed back by the wind force correct?

If i have something to hold onto and it's going 300mph and i jump, i'll land further back along the train as i will slow down in the air from wind force as the train as the train continues to speed underneath me, correct?

That is correct. When you jump on the train, you'll face a deceleration because of wind resistance, and will be blown back.

Great, thanks Solidus

I think you are on your way!

No problem. Fluid mechanics gets really tricky, though. You can also consider the dimensions of the train, and how air flows around it. If you can position yourself far back from the "nose" of the train, where the flow of air is less laminar and more turbulent (in the region where there is greater separation of air flow), you will not feel the full effect of the oncoming air that's being blown towards you.

So... if you're crazy enough to ride on top of a bullet train that's traveling at 300 mph, just make sure to stand away from the front. You might stand a chance of survival .

You're just saying that to make me feel better!

He'd be electrocuted before that

I'm a mechanical engineer . It just seemed like the type of question I'd be able to answer.

You're doing it wrong

What if the guy is the one who is cheating...and the opportunity to cheat is forced on him because of his reputation for that act.


Would it still be that he is doing it wrong?

I don't believe that surface of a bullet train is electrified, since it runs on electromagnetic propulsion and is levitated off from the rail. But, there should be a build up of static charges along the surface, due to friction from air - similar to an airplane. Nothing that would be fatal, though.

You're doing it again!

 

[devilof76]

Yeah, but...what if you're more aerodynamic than the average bear?

Bullet trains still use a 25,000V AC overhead supply. I was referring to that. The maglev trains are supposed to be opened for public usage in 2014.

Uncanny Web Slinger is an average bear??!

Nova should wear an electrically insulated suit, then!

If you're wearing parachute pants, you can pull of dance moves like this!

That suit looks somewhat like Prof.......you are such a tease!
