My friend and i were discussing this. There is not enough information
in the orginal question to determine anything. Depending which way you
argue the various variables, it could work either way. The people who
are saying the plane will fly are saying that the prop pushes against
the air and thus will eventually fly, the people who are saying that
the plane will not fly are assuming that the prop(or jet) is only
giving enough thrust to equalize the resistance on the wheels bearings
etc, thus the plane will stand still. define some variables, define
speed(wheel speed, ground speed, air speed) the original poster(at
cecils site) didnt give us enough info, and used the term speed and
move in more than one way. he also a plane standing on a runway, then
it moves, but then the conveyor moves. which is it buddy? if the plane
starts to move, it will take off. uh oh, here i go again, getting lost
in the details, now i think it will take off. its almost akin to
asking, if you fire a gun into a crowd will you kill someone. a lot of
people would say yes. what if the bullet went between people, what if
it was a blank, what if it was a blank and then some guy had a heart
attack, what if superman stopped it. define variables and argue it
either way, the answer is yes and no, it depends, and thats the
wonderful thing about these questions, it gets us to think, thats why
we are the top of the food chain. animals might have said, i dont care
weather it takes off or not, im outta here so it doesnt eat me. other
animals might have tred to eat it. aluminum or wood or fiberglass or
steel is not very edible to us, so we talk about it. its a great world
isnt it! if you need to be right to prove your intelligence, go on
jeopardy. to me, i gotta go flying, and i havent seen any conveyor
belts at OUN, so im outta here!
