How much weight can an aircraft wing hold?
When a tilt-rotor aircraft, such as the V-22 Osprey, flies through the air, it does so with specially designed rotors, shifting between acting like rotating helicopter blades and regular airplane propellers. But that flexibility means the aircraft’s wings must bear the weight of the propellers and the tilting mechanisms.
That creates an engineering problem: How much weight can a wing hold? Students in Aimy Wissa’s class MAE 323: Aerospace Structures performed the semester’s final project by building balsa-wood scale-model airplane wings. They made weight projections, and then put them to the test by hanging increasing amounts of weight from their wing until it broke.
Several of the groups saw their wings, outfitted with additional safety factors, bear quite a bit more weight than they projected before the wood cracked.
“That’s ok,” Wissa said. “As students learn to design things, in the beginning they’re very conservative in general, until they gain more confidence in their analysis. Then they tend to design near the limit. This is a good stepping stone towards that.”
In this video, Wissa and graduate student Hannah Wiswell (right) help the students conduct their experiment. Also featured in this video are juniors Alexander Liou (black T-shirt), Carrie Geisler (black shirt, putting on the weights), Jimmy Tran (red shirt), and Julia Hutto (tie-dye shirt).

      I am not an engineer but wouldn't that test an extreme case. Such as what is the max force that the wing can support when attached to the fuselage. If any force exceeds the force created in this experiment than wing is likely to detach from the fuselage which is what they may have been testing. Meaning, a point force at the wing tips should generate more tourqe at the failure point than at the base of the wing making that the theoretical maximum weight the wing can support.

      @@carlosfontanez9804 Yes, essentially your idea is about right, but there is no reason to test an entire wind this way since its always going to break at the root then. All they can see in this test is how strong the wings main spar is at the root and you could just forget about all the other structure. The point of testng models and mockups like this is to see how the entire structure behaves and to test a load that is, even today, almost impossible to calculate perfectly right. Hanging it from the tip will remove all that valuable knowledge from the test.

    A few summers ago, my wife, son and I went to the Princeton telescope to look at the stars (usually available every Thursday evening in the summer). The PhD student hosting the event was specializing in space exploration. I asked her if she could name the one Princeton grad that went to the moon - and to my dissappointment she could not - in fact, she could not name 1 of any of the Mercury, Gemini or Apollo astronauts- not even Neil Armstrong. Needless to say, I was quite dissapointed.

    Then why did he work in finance if books are his "passion"? He studied electrical engineering - then worked at a hedge fund. Not related at all. Clearly he's just chasing money, saw a trend and capitalised off of it - as he states in his earliest interview. This is all the philosophical bs afterwards to seem a visionary and raise stock prices.

    Making the world better often has the consequence of making it worse. Trying so solve problems technology creates often creates more problems in a perpetuating cycle. The thing that's urgently needed in today's world is slowing down and letting society (mentality) catch up to the enormous change technology has gave us. Technology and entrepreneurship can be both good and bad and right now it's bad in the way that it's moving faster than culture can catch up to protect our planet aka our own health before it's overrun. I don't think anyone truly understands that concept yet when they are brainwashed so much into solving problems technology gave us and being innovative instead of going back to their roots. Go back to Silicon Valley please and leave us alone here in Nevada. People spend their careers making the world worse then they seek beautiful places to retire and then turn them into another oppressive wealth inequality tech-hell.
