Critical Thinking 101

I feel strongly both ways!

Bird: When it enters the plane, it displaces air (reduces weight -- infinately accurate scale) but doesn't the fact it is in that airspace instead increase the weight?

 

[Rick Murchison]

Well, since the typical transcontinental airliner takes off at way above max landing weight, I hope it makes it down to that before it arrives. Otherwise they're liable to bend - or break - something.

You should have really twisted their minds and asked them where they would bury the survivors if the plane crashed directly mid-way through flight.

post a tougher one

You put a refrigerator in a perfectly insulated room, plug it in and open the door. Does the room get warmer, colder or stay the same?

Ps. Still relatively easy.

Well, Roakey, wouldn't that depend upon whether or not the refrigerator was operating before it was placed in the room. What is the ambient temperature inside the refrigerator when it was opened?

God, I love that one!!!

Now, if the plane was flying over New Jersey, it would have emptied its waste tanks and therefor would have been lighter.

We got a place for guys like you in joisy...

Well, if the bird is flying inside the plane, the lift of the wing has overcome the pull of gravity to the point that the up and down forces have neutralized themselves resulting in no effect upon the gross weight of the aircraft.

No it wouldn't.

Are you sure?
1. The bird displaces air which has weight, even if negligible.
2. I don't think the bird becomes "neutral," it is just exerting a downward force ... and doesn't that impact the weight as reflected by the infinitely accurate scale?
