IB physics extended essay HELP!! tis the season to start stressing over extended essay and i need help. i am planning to investigate how different angles of airplane flaps affect the lift of the plane when the plane is taking off or landing (because thats when the flaps come out)- you know how at a greater deflection the airplane can fly at a slower speed, etc.. anyways, you can see that i haven't exactly formulated a specific research question but its going to be something along those lines, but does anyone have any suggestions for how to narrow it down? also, for the experiment i need to build (a) model wing(s) to test out in a wind tunnel, but im not sure what to build it out of. should i have a single wing that has adjustable flaps so that i can adjust it at each trial? or should i have different wings for each angle i want to test? and any suggestions for what i can make it out of? my teacher was suggesting some material you spray around a mold, and then it hardens into that shape.. but other suggestions or ideas are very very very welcome. in fact being awaited. thanks!
