stupid questions

[jay]

right this ones for questions non tile related but things you don't understand most answers accepted ask a question and view answers simple (bit like how the sun works)


question 1

with BP probs and an estimated 19000 barrels a day being lost into ocean whats going in were the oils coming from//////// will sea level drop or will there be an earthquake //// go for it:8:

 

[DHTiling]

err i know how the sun works... but BP.. god knows..:lol:

 

[jay]

yeh the sun answer still baffles me a bit but the answer was to long to argue with:lol:

 

[DHTiling]

good though..:lol:

 

[nybor62]

thats one for stephen hawking

 

[enduro]

Land fill...or sea fill...:lol:

 

[jay]

its a fair size void:8:

 

[paul flight]

oil is replaced with water??? i think or there is a bloody big hole a :yikes:

Heres one that always produces a few different view points,

Could a plane take off from a conveyor belt, the conveyor belt isnt motorised, it just moves when resistance is applied to it, eg, if you stood on it then walked forward, the conveyor would move backward, like on of those non motorised treadmills.

My view is that the plane would take off as it would still move forward, becuase the wheels on the plane arent what push it forward, the jet engines do, do there wouldnt be any direct pressure applied to the conveyor belt through the wheels, (the brakes on the plane arent on). The wheels are just their to stop the plane scraping along the tarmac. So the jet engines would push the plane forward and it would take off, presuming it could reach the required take off speed.

It would be different for say a car, which gains speed through the wheels applying pressure to the conveyor, which would just move at the same speed as the car, and it would go no where, like a rolling road.

What do you lot think? could the plane take off

 

[merlecollins]

Yes, but would the wheels not still go around when the jets moved the plane forward, thus activating the conveyor belt??

 

[Olz]

I think that the wheels would turn slightly due to some friction, but the key point in my mind is that the conveyor moving wouldnt prevent the plane from being propelled forward, becuase a plain relied on the thrust from the engines to push it forward, not friction from the wheels. In the same way that a jump jet simly lifts itself into the air, then changes the angle of the jets to push forward. The wheels only serve to stop the plane scraping along the floor.

I just cant image why the convyor would actually cause the plain to go backwards on it. Or remain still. It would be a different story if a plane accellerated through the wheels then used the engines when in the air though, as clearly, like a car on a rolling road, it wouldnt go anywhere.

I stand to be corrected though, im no scientist.

Can't get in to the airoplane thing, my break nearly up, but, Jay, do you think BP has found the answer to global warming?? Sea levels not rising anymore more, because they found a plughole to drain the sea into?? They deserve a medal then :lol: :ban: :lol:

i think and can be corrected that a plane needs a volume of air under its wings to create lift thus needing speed to achieve lift but its only a thought but oli you got me thinking ta:8:

 

[Prem Tiler]

here is one for you. China is exspencing huge hole apairing in the landscape for no known reason. I wonder if is to do with the oil being lost from the other side of the world causing huge voids in the planets structure?

Just a thought?

 

[mikethetile]

unless the jet was a vtol it would remain on the conveyor belt

its not the rearward pressure from the jets that gives you lift but the differance in air pressue over the wing
