Dope Tech Episode 2

<<@paulb9156 says : It’s like a McDonalds burger.>> <<@ClassicsDecodedPodcast says : For the bicycle tire the limiting factor may not be the pressure but rather the integrity of the material wrapping the coil since normal friction would wear it out over time as well.>> <<@ImKiddingBroDontTakeMeSerious says : How come every video from “space” we have we can never see the earth in the background ? The fact people believe the moon landing is real is completely mind boggling to me.>> <<@cozyandahalle says : Building wheels for "other worlds" is like building wheels for the afterlife. Not needed. We need better wheels for down here on Earth.>> <<@Toushi_Lkr says : On 0:11 The wire says "NASA" . Is that intentional?>> <<@GoodCitizen2005 says : Can you suit up a car with those wheels and drive it on lava please?>> <<@Haltzo says : They need to remove the stupid cable you can shoot>> <<@smileystar21 says : noice hn>> <<@hasibulhasan8755 says : Dr. Padula looks exactly like Derek. At first I thought they were brothers. But Muller is a German title, where Padula is maybe rooted in Iberian demography.>> <<@GeometryofShame says : That zipping is WILD! Those crystaline atoms snapping into and out of place.>> <<@GeometryofShame says : I want to make toriodal wire mesh tires, but I have no idea how to go about doing that.>> <<@Gamegirl19934 says : 18:41 holy voice crack>> <<@steviemoney says : NASA never see the damage my wife can do with a curb>> <<@OperatorPuski says : The problem with stuff like this is to ever get to market takes decades let alone trying to wipe out an entire industry putting every tire shop out of business.>> <<@Silvio-gk says : So why hasn't NASA gone to Venus>> <<@bartwilliams4478 says : Great ideas but for now the product is tremendously expensive>> <<@VariableX112 says : "and it will"... SNAPP BACKKK TO REALITY, OH THERE GOES GRAVITY!>> <<@delatroy says : Surely a spring will snag and rip the entire wheel off?>> <<@idontknow2074 says : That was a bb bro>> <<@6Jazzbanana9 says : Wouldn't the carousel used to test the wheels be somewhat inefficient for testing? I was under the impression that propelling your body weight forward in space across a relatively unmoving mass is different than maintaining the same spot in space relative to a mass moving in the opposite direction you're facing. Like how running on a treadmill is different from running on a paved street. I imagine the carousel test is one of many given the fully built replica moon & mars terrain.>> <<@joejackson4202 says : Hope they are willing to share this tech with Canada. I need bulletproof bike tires because I live in Hamilton, Ontario.>> <<@hakimhakim-d7e2z says : Daaamn that nitinol memory shape was craaazy>> <<@LayboobooDestroyer says : "All the innovations in america are things that the government and military had years before the civilian market did, imagine what they have now that they arnt Showing">> <<@Ford4life885 says : So that’s what being done at the research center by Hopkins int airport>> <<@TheDotplus2 says : FIX BEDROCK MOJANG>> <<@DJDUDE-Topic says : Hi>> <<@jude-banksjosiah8845 says : Hera me out not an original idea Airless Basketball>> <<@Dismal1883 says : I thought those wing flap thingies on plane wings were controlled by the pilots. I’m always fascinated by scientific based engineering.>> <<@ColletteBardell says : Thank you for the great content!>> <<@tksbelcher3084 says : That one guy thinks a normal bike tire is at 100psi?!>> <<@Augmented_AI says : This will be death of the tire industry 😂. No more expensive tires or tire replacements.>> <<@Tao4Now9393 says : Was this before private equity ruined the channel?>> <<@EdwardDornan-p9m says : Wow it doig steal u get normal stealth and get it up then u hard it the u clean heat again don’t quench in oils oil a drop or oil will make a crack so clean very well a het up again and then Qunch in water only to get spig steal hard bassklu het up 3 x quench 3times and u make sprig steal shape it before 3 x>> <<@ExtremeylZos says : Why isn't this in every vehicle then.>> <<@KHAN_ACADEMY_FAN says : 2:11 of course you can't get away. Your camera man can be assassinated>> <<@keymail21 says : 😍😎🚀🚲🚗🚙💡👏>> <<@AstorJohnson-Perry says : I have an idea, you could make cubes or triangular prisms and use them as ammunition, when they are heated by the gunpowder, the form into an aerodynamic shell.>> <<@richarddecredico6098 says : important to note: they kept the part that is round>> <<@JasonTraub-c8i says : this guys videos are stupid April fools>> <<@HyungnamGu says : The Four Stages of the Shape Memory Cycle 1. The Austenite Phase (High Temperature) At high temperatures, the material exists in the Austenite phase. This crystal structure is highly ordered, symmetric, and "rigid." This is the material's "parent" or "memorized" shape. Any configuration set here becomes the baseline the material will always try to return to. 2. Cooling to Twinned Martensite As the temperature drops below a critical point, the atoms rearrange into the Martensite phase. However, to avoid changing the overall external shape of the object during this transition, the crystals form a "twinned" structure. Self-Accommodation: The crystals tilt in alternating directions (like a zig-zag pattern) so that they cancel each other out on a macro scale. The piece of metal looks exactly the same to the naked eye, even though its internal structure has changed. 3. Deformation (Detwinning) When you apply stress to this cool, twinned martensite, it feels "soft" or plastic. Instead of breaking atomic bonds, the stress causes the "twins" to flip and align in a single direction. This is called detwinning. Macro Result: The material undergoes a large, visible deformation (often up to 8% strain). Residual Strain: When you let go, the material stays deformed because the detwinned martensite is stable at low temperatures. 4. Heating and Recovery This is where the "memory" happens. When you heat the material back above the transition temperature: The detwinned martensite becomes unstable. The atoms are forced back into the high-symmetry Austenite arrangement. Because there is only one way for the atoms to fit into the Austenite lattice, the material must physically move back into its original high-temperature shape to accommodate the shift.>> <<@Wolfgang-Albrecht says : Question: How effective are these mesh tyres in extreme muddy conditions? Will they work? How will you remove the mud from the mesh?>> <<@Latenthistories says : ❤❤❤❤❤👍👍👍>> <<@TamLe-fi2gq says : Shape memory alloy: somehow first learned about this in 1998 when Solid Snake was conned into activating Metal Gear. How is Kojima always so ahead of his time. Hope other players recognize this immediately… that huge backtracking sequence to heat up and cool down the keycard>> <<@gator1984atcomcast says : Forget wheels. Wheels need roads. Use legs or just hopper.>> <<@fanoftbe says : 12:31 Holy prediction>> <<@AppliedCryogenics says : I know every crazy uncle says stuff like this, but industry will never abide a "forever-tire".>> <<@me.ssiah0 says : Ok, so why don't we make car tires with this material while still using a suspension system?>> <<@spiralae says : Unfortunately metal tire damage road lol>> <<@CharlesIsabirye says : I wonder, how does tht bike tyre act up when u push the bike wheel above 40km/h... Will the tensile memory let u down?>> <<@red1tao284 says : I'm starting to become convinced that science is magic>>
