Dope Tech Episode 2

<<@nthieme7 says : Smartest part of this video... hat over the crotch.>> <<@Noah-z4x7u says : 3:29 even if a bullet is shot always protect ur jewels 😂😅>> <<@xaosnox says : I LOVE that accent! They is "Theh-ee" and poured is "poh-rid". It doesn't sound like the East Coast. North West? It makes his "eternally adolescent" voice that cracks like a 12 year-old sound very young.>> <<@xaosnox says : 4:06 I wonder how many people stopped watching at this moment. Av lot, I'd guess.>> <<@IshanthYaramati says : I showed this to my physics teacher and he said it will not be deadly unless it is a heavy object like a pencil box>> <<@Slinkyreal says : So heavy the coin is more dense than a black hole>> <<@EvanJohnson-u9d says : It seems to me that Adam Savage should’ve been an arms dealer>> <<@WhiskeyTangoFixit says : Seems kind of dangerous hoisting the full bucket out and dumping it manually. What if you bobble it and drop the bucket full. It then becomes a test of running while shitting oneself.>> <<@Windows8_2012 says : Now they're gonna have to drop nickels instead of pennies now that the penny has stopped being made.>> <<@kayraaktukmak says : 0:59 no it wouldnt u need to be 4.5 km up in the air for bullet speed ignoring the air drag>> <<@allin1k7 says : Guys it's raining pennies!>> <<@AsapRanking says : 1>> <<@HyungnamGu says : The lower limit of the energy required to fracture a human skull is generally reported to be around 14 to 15 Joules (J) for direct impacts, although some, lower-bound studies have indicated that fractures can begin to occur with energies as low as ~4 Joules (depending on the specific skull area and loading conditions). Key details regarding skull fracture energy: Threshold Range: Research into blunt trauma suggests a fracture threshold for the skull ranges between 14.1 and 68.5 Joules. Experimental Minimums: Specific studies on frontal bones have shown that fractures can occur at lower energies, with some measurements averaging around 3.95 ± 1.18 J. Force Equivalents: While energy is measured in Joules, the required force to fracture a skull is often cited as being around 2,300 Newtons (roughly 520 pounds). Context: These lower limits typically refer to thinner areas of the skull or more vulnerable spots like the temples.>> <<@HyungnamGu says : When an object falls, gravity pulls it down, and air resistance pushes it up. As the object falls faster, the air resistance pushing against it increases. Eventually, the object reaches a speed where the upward force of air resistance perfectly balances the downward pull of gravity. This is called terminal velocity. At this point, the maximum air resistance an object can experience is exactly equal to its weight. Because a hammer weighs significantly more than a feather, the absolute maximum force of air resistance acting on it (measured in Newtons) is much, much larger.>> <<@peter-x5b4d says : his dihhh after this be like>> <<@TheNapTaker says : 3:15 brave of you to lay down with only a fedora as a dick guard...>> <<@sakshamjain4640 says : at 5:58, It should be Mass to air resistance. Even though both are correct but mass seems more logical.>> <<@HyungnamGu says : As the object falls, air resistance (drag) increases with speed. Finding Stability: To achieve the most stable orientation, the object will naturally reorient itself to maximize the drag force acting on it. Highest Resistance: The orientation that creates the maximum drag (highest air resistance) also allows the object to reach its lowest terminal velocity fastest. Physical Example: A falling object with, for example, a heavy end and a light end, will usually flip over and fall in a way that maximizes its cross-sectional area (e.g., falling flat or with the broad side down), which maximizes the air resistance and minimizes turbulence, leading to a stable descent. Terminal Velocity: The point where the highest resistance (drag) balances the force of gravity is the moment the object stops accelerating, becoming the most stable, constant-speed descent. In essence, a falling object acts to "maximize air resistance" to reach a stable, non-tumbling, or minimal-acceleration state, often referred to as finding the maximum air resistance orientation.>> <<@Nachos-sk7od says : 20:20 I'm a bit confused😇 2000th of a joule = 0.0005J two thousandths of a joule = 0.002J>> <<@DrJack717 says : He actually said the hammer/feather wrong. (5:30) He said the reason the hammer falls faster, he initially said was due to its weight. He then changed it to ratio weight to resistance which is correct, but in the original should be the surface area to weight (plus shape) that would be the factor, not the weight alone. A 10 lb feather would fall slower than a 10 lb hammer.>> <<@scotthawkins7128 says : When I was a kid I would tell people that if you dropped a grape from the Empire State Building and if I was talented enough catch it in my mouth it wouldn’t really hurt much if at all. They all mistakenly thought it would kill me or put me in the hospital. I tried to explain air resistance and it was difficult for them to grasp. I tried using a parachute as an example. The parachute weights way more then the grape so, is it going to hurt me too? Some people get it some people don’t.>> <<@everythingatonce6904 says : 20:21 how is 2 thousandth of a joule 0.002j>> <<@300pingdog says : 3:17 what if it landed in a very specific place>> <<@KhatimOpYou says : 21:14 this is the first time that someone said i love learning even i dont know>> <<@MjolnirVIII says : THROW THE BUCKET>> <<@Veectory says : Goodbye to the penny : )>> <<@brianlittle717 says : Wouldn’t it just burn up in the atmosphere?>> <<@haireusapchamlak8332 says : For the pen to work, you need to hold at the back end and drop, not throw>> <<@REDSTONENOOB. says : you forgot about australian youtubers>> <<@DracoMalfoie says : parent: "you think money just fall out of the sky?" me: yeah>> <<@SoggyCorner says : 19:05 w monkey ace shoutout>> <<@wilfreddv says : You're telling me 67 joules is the upper limit?>> <<@sanchitsharma6756 says : 11:50 it can drink now>> <<@gordonelliott7870 says : Terminal velocity of the coin is complex, unlike for example a sphere that would be much more simple (but not of no complexity because of turbulence). Demonstrated by the people changing their "cross section" in the air tunnel. The coin flips (in a turbulent way) which is a variable cross section. Edit: Wow, didn't get that far, completely documented! Glad he didn't accidentally let go of the bucket. What is the terminal velocity of a bucket?>> <<@ZAGTVKS says : Is this why there is a penny shortage?>> <<@Keln02 says : Showered in money. Living the dream.>> <<@vsdktbkm5012 says : 16:51: It is called the "Munk Moment". Forces a stick to orient perpendicular to the flow of water in stream.>> <<@tanchauee1165 says : before watching the video terminal speed get into my mind>> <<@Girlsjustwannahavefun2321 says : Who has seen the movie Final destination I believe V.? This was the scene with the penny…I’m fascinated by that movie 🎥 because of its engineered ideas 💡 to die 🙃>> <<@LessSoyThanYou says : Bullets tumble in nearly any orientation they’re shot, even parallel with the Earth.>> <<@ZodyZody says : Boys will be boys lol!>> <<@geoffwallick says : Terminal velocity of a penny is like 65mph>> <<@Wannabe_author says : If i throw it with some mean spin I am killing a mf>> <<@SillyGoose2024 says : dude this was interesting for like 3mins. i cant take 22 minutes of this interesting yet unimportant info>> <<@ZelosZelo says : pretty simple answer, the terminal velocity is up to about 70mph, this is about 1.22 J of energy when it hits something solid, like concrete. Which aint crap, a little girl can hit harder.>> <<@internetproof says : Idiot>> <<@Thats_some_bad_hat_Harry says : seems like Derek could find a way to drop something from high up without a personal helicopter>> <<@cyrusonahill7183 says : what happens if you drop an anvil from the top of the empire state building 🧐??>> <<@erwinsmith5381 says : صلى الله على محمد>> <<@xiodcrlx says : you needed to check another object - a modern smartphone trown from the top!>>
