This isn't for homework help, but I really need the answer? xD

Okay, so if an animal weighed 1200 pounds and needed a wingspan of 72 feet to fly, what would a 300 pound animal need for it to fly?

Thanks! =D

If you divide 72 by 1200, you will get an answer whose units are feet per pound. Multiplying feet per pound by the weight of your animal will cancel pounds and give you the answer in feet.

Also I would like to know the solution please :D

There's a big honking assumption here that wingspan scales linearly with weight.  Almost certainly not true.

anonymous · Answer

True, but unless WolfLover is current doing a unit on a particular type of relationship, a linear ratio is the go-to default.

@Richard_Feynman thanks!

Oh, I'm not trying to suggest the problem should be done any other way, just that it doesn't represent reality :-)

anonymous · Answer

If the width of the wing were constant and you ignore the weight of wing itself, I think a perfectly rigid wing would actually follow that relationship.
