Even if you don't know anything else about airplanes, you know the wings are a pretty important part of the whole system. It’s the one idea we took from birds, after all. Not counting the absence of feathers, the most significant change human engineers made over the original design was that plane wings tend to not move. Or do they? In fact, a plane's wings might not flap, but they can certainly bend. In fact, they bend quite a lot for something we're used to thinking of as completely solid and stiff. If you've ever been seated on a plane with a good view of the wings, you might’ve noticed they tend to bounce up a bit during turbulence. What causes this to happen, and how far can a plane's wings bend before they break? Other videos you might like:

– The good news is no, the wings aren’t about to come unscrewed and fly off on their own. In fact, it’s precisely because they can bend that an airplane's wings don't break.
– Imagine the wings as shock absorbers in a car. When you drive over a bump, the shocks absorb most of the impact, giving you a much smoother ride.
– If the plane's wings were rigid, even the slightest turbulence would reverberate throughout the entire aircraft.
– There are Japanese pagodas that have survived centuries in one of the most tectonically active places on Earth, all because the timbers were able to flex instead of breaking.
– The first and most significant thing is the material. You might have heard that most planes are made from aluminum, and unless you’re taking to the skies in an early 20th century era biplane, that’ll be true of pretty much any aircraft you climb into. – Aircraft-grade aluminum is an alloy of aluminum and zinc, sometimes accompanied by other metals such as copper, magnesium, and lead. – Adding to the strength of the wing is a structure known as the spar, a metal bar running the length of the aircraft's wings.
– Some fighter jets, such as the American F-15 Eagle, feature titanium spars, and many newer aircraft incorporated specially designed composite materials.
– According to experts, the only way a plane’s wings could break off, was if the airline that owned it was guilty of a truly horrendous degree of negligence. – As with a plane’s wings, helicopter rotors are not one hundred percent rigid. They’re actually even more flexible and will visibly hang down when the vehicle is on the ground.
– The flexibility in the rotors serves the same purpose as in a plane's wings: reducing the effect of vibrations and making the aircraft easier to control. – The next time you jump on a plane for a quick hop across the pond, don’t panic when you see the wings doing a little shimmy. It might not look like it, but they’re functioning exactly as intended. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

More Why Plane Wings Never Break Videos

Coming of age and kissing your teenage years goodbye is an exciting step towards the whole new life that awaits you. It’s a good time to drop the extra weight that slows you down. Deciding which things are better left in the past might be easier than you think. For example, do you really need all those dated magazines and comic books? Most likely, none of them will become an all-time classic worth millions of dollars for collectors. Even if one did, you wouldn’t be able to find it amongst the mess you have. And what about toys from childhood? They sure hold some good memories, so pick a couple of them that are the closest to you. Everything else is better left behind! Other videos you might like:

4 Signs You're Going Through Puberty https://www.youtube.com/watch?v=YSi1cDPftbA& TIMESTAMPS:
Dated magazines and comic books 0:20
Mismatched socks 0:36
Worn down clothes 0:56
Toys from childhood 1:25
Sports gear you barely touched 1:54
Kitchenware from your parents’ house 2:18
Plastic forks, spoons, and knives 2:47
Ball of cords and chargers 3:16
Your old cell phone 3:45
CDs and DVDs 4:22
Used batteries 5:00
Melted scented candles 5:24
Dusty guitar 5:50
Posters of your favorite band 6:25
Bottles of anti-acne lotions 6:53
Clean your blog and social media 7:15
Crafting materials 7:42 #everydaylife #adulthood #brightside SUMMARY:
– You can try to wear mismatched socks of the same size, but when you’re over 20, it’s not about if someone would see it anymore. – Somewhere beyond age 20, the growth of the human body slows down dramatically, and you can finally get yourself some nice quality pieces of clothing.
– All the gear from every sport you’ve attempted throughout the years is just collecting dust on the shelf. If you’re over 20, donate it: there are lots of teens that could put it to good use. – If you want to cook for yourself – and you should try, because it’s cool – you need your own kitchenware that will suit your own specific needs and tastes.
– The stingy thought that one day you’ll find yourself needing one of them, and regret terribly that you threw them away, is the only thing keeping you from tossing out the useless cords.
– All those basic outdated cell phones, flip phones or sliders – it’s kinda even funny to think about them in 2019! – Even if you’re a music fan, you should know that there are some other analog formats on the rise, like audio tapes and vinyl. Yeah, they’re even older, but ironically, they’re much less obsolete than CDs.
– The environmental damage an empty battery can cause is pretty bad, and leaving them lying around in your own room isn’t a great idea either. – The melted wax in candles naturally traps dust and just looks messy. Even if you think you may want to use them another time, they won’t be as pleasant anymore. – I also once thought I was going to become a rock star, and now I have an instrument in my closet with rusty strings. Things won’t always go as planned, and there’s nothing to blame yourself for. – If you’re older than 20, posters of your favorite band don’t belong on your walls anymore. You’re an adult now and you can show your appreciation of someone’s art in a much more personal and cool way. – Pay some extra attention to those older posts you made in your early teen years and try not to lose consciousness from laughter or embarrassment. – If, at some point, you feel inspired to have a hobby again, start from scratch. Since it would be a more mature decision, you’ll progress much faster. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz

More 17 Things Everyone Should Get Rid of By Age 20 Videos

“The Universe is constantly expanding.” You’ve heard that phrase plenty of times, yet have you ever really wrapped your brain around it? If the earth is a planet in the solar system, which is only a part of the Milky Way Galaxy, which is one of countless others in an infinite universe, and the whole thing just keeps growing – what IS that?!? Imagine if your house, rather than being located on a quaint little street with neighbors, squirrels, and ice-cream trucks, was just sitting in the middle of nowhere. Just a whole lot of uninhabitable space farther than you could walk, drive, or see. That house is our galaxy, floating around on a giant sea of nada. And that “nada” is only getting bigger as the universe expands exponentially… Other videos you might like:

… And what does it consist of? 7:14 #space #astronomy #brightside SUMMARY:
– It all started with the Big Bang. Within an itsy bitsy fraction of a second, the universe was born, and this baby had quite a growth spurt! – The Milky Way is part of a group of galaxies known as the “Local Group”. The Local Group contains tons of dwarf galaxies.
– The Local Group is itself just a tiny piece of an even larger group of galaxies called the Laniakea Supercluster. It has over 100,000 galaxies, ours being just one of them.
– Next to us is a distinct and vast area of nothingness that astronomers aptly refer to as the Local Void. – Our Milky Way is moving away from this thing at 160 miles per SECOND!
– Gravity makes galaxies move closer to each other, so these voids expand as objects move away from them.
– Astrophysicists hope that these space voids can tell us something more about Dark Energy.
– The study’s lead author, R. Brent Tully, was also the head of the team that first discovered the Local Void back in 1987. – Using the information they gathered by observing and measuring what they could see and what they had to infer, they were able to build 3D maps of our corner of the universe. – The 3D map shows that just as the universe is expanding, so is the Void. – Over the last 30 years, astronomers have been working hard to understand the movement of the Milky Way, Andromeda, and dwarf neighbors. They all appear to be different from the overall understood expansion of the Universe by over 372 miles per second.
– So, is this void next to us actually just 150 million light-years of nothing? Yeah, pretty much.
– Ironically, because of all the nothingness there is inside of space voids like our own, these things still find themselves filled up with something. And that is what’s known as “Dark Energy”. – And scientists aren’t sure what it is, but the best guess is that it has something to do with the vacuum of space-time. – Dark energy is free to do its thing and expand and expand and expand some more. The expansion of the universe happens mostly within these voids, and as they push out on their surroundings, they drive more galaxies apart.

You might also stumble over your words. – A confident person will have a smooth and steady tone, will keep their volume at a comfortable, stable level, and their words will come out at an even pace. – One study found that there’s a correlation between how attractive or pleasant your voice sounds and how desirable you are physically.
– Talking slowly in an even and warm tone gives the impression that you’re in control and at ease, a good indicator that you’re perfectly able to keep your emotions in check. – A nasally voice makes a person sound demanding, calculating, and cold. A person with a voice like this is unlikely to be taken seriously as well.
– Successful people’s voices tend to be of a lower, warmer tone. – A creative person may not actually talk much, because they’re daydreaming, people-watching, or thinking deeply. But when they do talk, they certainly won’t be boring to listen to! – In the middle of a lie, someone’s voice may get shaky and change pitch or tone.

More What Secrets Your Voice Reveals About You Videos

Unless you’re an astronomer, you probably don’t think of stars as moving all that quickly. You might not even know they move at all. If that’s the case, you’d be surprised to learn that a star called S5-HVS1 is zipping through our galaxy at over ten thousand miles per second. As with many of the best discoveries, astronomers found this rogue star entirely by accident. One o them was going through some of the survey data when he came across some unusual readings. He was looking for stars with unusually rapid orbits, but was surprised to find one fleeing the galaxy at record speeds… Other videos you might like:

Why is it getting expelled from the galaxy? 3:10

The supermassive black hole at the center of our galaxy 5:57
Two theories about this star 7:05 #space #stars #brightside SUMMARY:
– It’s hard to tell by looking at them, but stars are in constant motion, orbiting the center of the galaxy just like the Earth orbits the sun. – S5-HVS1 (you know, let’s just him “Speedy”) is no ordinary star, and its movement isn’t at all normal. This recently discovered star is racing toward the outer edge of our galaxy, having been ejected from its orbit at a velocity never before seen in recorded history. – Astronomers classify this white-hot ball of plasma as an A-type main-sequence star and have estimated it to be more than two times the size of the Sun. – When a star goes supernova, it doesn’t always explode evenly. These lopsided detonations not only expel a few dozen Suns worth of gas and plasma, but also hurl what remains of the star through the cosmos at almost half the speed of light. – But Speedy isn’t a neutron star. So why is it getting expelled from the galaxy like a spare tire improperly secured to the back of a truck? – Things can get pretty wild when black holes are added to the mix. In this analogy, they’d be somebody’s loud friend who’s always around, leaving dishes in the sink and drinking the last Coke without asking. – When these binary systems drift too close to a black hole, its mass disrupts the delicate balance of gravity and momentum that keeps the system stable.
– If you ever swung your keychain around your finger only to have it soar out of reach, you’ve seen a version of this in action. – What differentiates Speedy from the other black hole ejections is the star’s comparatively low mass. – To generate that much energy with a star that small, the black hole that disrupted Speedy’s orbit would need to be extremely massive. – Before being batted across the universe, Speedy would’ve been paired with a second, much smaller star. – Both stars originated in the supermassive black hole’s accretion disk. – Astronomers may not have a perfect answer yet, but Speedy is still under observation and there’s no doubt more to uncover. – For now, astronomers are eager to find more hypervelocity stars in hopes of gaining a better understanding of what’s going on in the Galactic Center, and how mass is distributed across the vast collection of stars we call the Milky Way.

More The Fastest Star Ever Is Going Through Our Galaxy Videos

Do you notice every little detail about your surroundings right away? If yes, then you didn't miss the fact that all planes have a green light on the end of one wing, and a red one on the other. Why do they have different colors? Actually, these high-intensity red and green lights, together with a white light located on the tail, are the plane's navigation lights. The red light is always on the left wingtip, and the green one is always on the right. These navigation lights are on at all times. Apart from navigation lights, planes have red rotating beacon lights installed on the upper and lower fuselage. Let's find out what they are for! Other videos you might like:

– Let's say, a helicopter's pilot sees red and white lights in front of them at night. This lets them know there's a plane passing from right to left. Green and white means the plane is flying from left to right. – When the red blinking light is on, it's a warning for the ground crew and other planes that the engines are about to start, and it's dangerous to come near. – And just like a car, a plane has headlights that help the pilot see the runway during landing and take off.
– Seeing the hypnotizing swirl on jet engines prompts the ground staff to stay away.
– The outer pane bears the most pressure, and the hole in the middle one helps regulate the pressure difference to make sure passengers don't experience a lack of oxygen. – There’s a magic button near the hinge under the armrest closest to the aisle that will make your trip instantly much more comfortable. After pressing it, you can freely move that armrest up, making it parallel to the back of your seat.
– When a plane takes off or lands at night or dusk, the cabin crew wants your eyes to get adjusted to the darkness. Usually, it takes up to 30 minutes to fully adjust to a dark setting. – Can a plane door open mid-flight? If, for some reason, this question worries you when your plane is about to take off, then let me put your fears to rest – it’s impossible.
– Statistics say that lightning still hits every commercial plane once a year. But in most cases, this leaves a plane with only minor damage, like a scorch mark on its surface. – Actually, all commercial airplanes are designed with seats and windows perfectly aligned. But when a specific airline buys a plane, it’s up to them to decide how many seats it’ll have.
– Most airlines insist that there is no safest seat. But the statistics of airplane crashes supports the idea that it’s at the back.
– Many airliners have secret, windowless bedrooms for the cabin crew that include from 6 to 10 bunks. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz
