@@kevinlasher2812 I think the professor was overconfident, put too much weight in weak arguments (like Derek getting into Blackbird many times??), and was also condescending as you suggested. Maybe he thought he would easily win $10000. The already existing treadmill-footage clearly showed the cart wasn't being "pushed forward"; there was no "bias" in that sense (the bias was in the professor's mind that people would be as silly as to do the treadmill experiment repeatedly and always "unconsciously" push it forward). But mainly, "the video falls short of providing evidence that the motion faster than the wind occurs with a non-negative acceleration and that it is not caused by the wind variability. " Derek's treadmill experiment clearly shows there is positive acceleration relative to the ground. Unless he was suggesting that somehow the wind behind the propeller acquires higer speeds, or to vary so much so as to get the negative acceleration he mentioned. Again, clearly not present in the treadmill experiments. It seems he is trying to look gracious "Oh well, I had to concede if I wasn't 100% correct". But he was just wrong. To me, the main issue was understanding how the "turbine" worked. In any case, he should have gotten himself fully familiarized with the problem (or maybe he actually was, and is playing dumb) before betting that amount of money...Apparently didn't even check the literature on the problem. The professor suggested the bet right? Kind of weird. Not sure what he wanted to get out of it. Maybe "school a youtuber"? Prevent the spread of what he thought was pseudoscience? In brief, arrogance got the better of him.

Very easy, the output speed is equal to the ratio of the input gear and the output gear, . regardless of the size of intermediate gears. There are no co-axial gear sets, only independent idlers, therefore one tooth is one tooth consistently through the train. The answer is 30/60, or 1:2. Output is 5 RPS.

@Reverend_Salem 5 місяців тому
especially since some of his concerns/challenges are actually valid concerns that should be tested for, with a "fail condition" (i.e. how the hypothesis can be disproven) the wind gradient for example, is a really good challange, because there is a diffrence in wind speed as you go higher, and a tall land based wind powered vehicle could make use of that to travel faster than the ground wind, even if the operator doesn't realise it. to disprove the hypothesis that the wind gradient is causing the vehicle to appear to go faster than the wind, you just need to show that the vehicle is going faster than the wind at the highest point on the vehicle. (or test in an enviroment where the wind gradient is minimal, like in a hanger with a fan model and a treadmill, probably with a treadmill set with a variable speed control to simulate the vehicle moving across the ground. that way twind speed, and the vehicle speed.) the gust hypothesis (a high gust of wind pushes you faster than the "normal" speed, which may look like you are traveling faster than the wind. The treadmill set up would also be a great way to disprove this hypothosis.
@user-vt4up5ij9d 5 місяців тому
@@Reverend_SalemThe treadmill test is flawed though. By holding the car on the treadmill, the force the person imparted was greater in the beginning as it not only kept the car at a constant speed but also used the resistance of the wheels to build up the speed of the fan to the point where the gust from the propeller exceeded the resistance of motor powering the propeller at the treadmill’s speed. As the fan got faster and faster, she had to use less force to keep the car still, and eventually had to use slightly more force in the opposite direction to keep it still . She was essentially charging the propeller like a battery. This would be like if there was a 30mph wind gust, but the resistance of the gears is increased such that cart can only reach 15mph and the rest of that energy is used to power the propeller. Then the wind gust drops to 15. You reduce the resistance of the gears so that all of the wind gust goes to pushing the cart forward, but the propellers still have inertia so they push forward with the energy built up under the 30mph wind gust. The cart will lurch forward faster than the 15mph wind gust, just as it did on the treadmill.
@Reverend_Salem 5 місяців тому
@user-vt4up5ij9d i ment a tredmill test where the fan pushes the cart forward, and the treadmill is calibrated to keep the cart relitivly centered. (i.e. the treadmill is reacting to the cart.) basically, like chasing the cart with a fan. the fan is actually the thing doing the pushing, the treadmill is mostly to make it so you dont have to run around a large area with a fan.

And I must say his points had a good foundation. Stuff like gusts of wind, different wind speed at different elevation over the ground, etc. I don't even think he is wrong with those arguments. Which are basically about external influences on the experiment. That is the reason experiments have to be repeated to assure that the result is not just based on those external factors.

Good point. I don't know if I've ever bet someone money about something I was 100% confident I was right. I'm sure they're well compensated in their professions, but $10K is still very different than betting $10. I don't think too many people, regardless of financial standing, would agree to such a large bet if they believed there was a fair chance they'd lose. Maybe the professor understood that (including as Derek said...a public bet to boot) and was fine with it, but I'd bet (let's stick with $10K ;) ) he was confident he'd win. So right...says a lot about one's character by paying up a solid chunk o' cash like that. Good character these days, is especially valuable.

You are correct. Just like the keel on the sailboat, the airfoil gearing constraint to the wheels ensures that for every unit of downwind travel, the airfoil is forced to make some specified unit ratio of crosswind travel. Remove the keel effect from a sailboat and it merely drifts downwind at some speed less than the wind. Cut the chain to the wheels and the Blackbird does the same.

Wow, one of the best engineering videos I've ever seen. And what an impressive cast of characters. I was especially delighted to see that Xyla Foxlin was involved I only recently discovered her to see that she's breaking the gender barrier in engineering. Also I'm curious to know if you have any thoughts on toroidal propellers. And I couldn't help but notice that the propeller blades were not faired into the spinner, that seems like an opportunity for just a little more Efficiency. Thanks for the education.

Now THIS is a very good example of a scholar who is really dedicated to learning, not oneself’s pride. I honestly think UCLA is blessed to have such an awesome professor!

The professor is going to be publicly known as a fool after this. He's going to be hearing jokes about this from students for the rest of his career. Even his wife will be pissed at him for losing $10k. I had a professor in engineering school that said it is impossible for an electric motor with a propeller on it's shaft to be able to lift it's own weight. I wonder if he ever sees these drones flying around and has reconsidered his position.

@@alexkram No. The professor was correct that the explanation was faulty in that there was a singularity issue. This prompted him to rethink a model which led to him believing that it wouldn't be theoractically possible. Turns out that if you use a nonlinear model for force and momentum, you get a perfectly convergent model for the power transfer.

I disagree a bit here. when established research gets confronted with a new theory which fits better you will still see friction from established research groups. Because they are invested in their theory, mentally but also in capital aspect. And that investment makes it really hard for the new better fitting theory to really win ground.
