14:15 "If you're not terrified of spinning things, you should be." is so damn true. The rotational inertia around high rpm & large mass machinery can do some insane and very, very not pleasant things to a human body.

[@ruthless_auto]

Absolutely. As someone that ran CNC machines for a few years, when they go wrong or when say a part is loaded wrong or unevenly, yes they can get very violent. More than once in my day I’ve had thing go wrong such as air pressure drop in the building causing CNC jaws to open while running and have had metal parts smash through the double pane glass windows on the machine doors as well as seen 500+ lbs machines jump off the floor while ejecting parts through the glass and shake the concrete floor. Luckily I’ve never been hit

[@innominatum9906]

@@ruthless_auto Yeah, lathes can be brutal and will absolutely destroy you if you arent careful. We run these Ø10"x20 really thinwalled plastic parts on a manual lathe as a finish op after CNC. Its usually something we end up having the apprentices do. Its very vital that they remember to put in the aluminium endcap at the jaws so they can actually hold onto it before machining. One guy didnt. The second the cutter touched the part it ripped it out of the jaws and shot it right into his face. Lets just say that he isnt our apprentice anymore and not because he/we doesnt want him to be. I also heard about a hydraulic sensor on a CNC that gave up during a run. Luckily the part was ejected into the machine instead of the operator - but that machine was totalled

Fun fact: that trick where Letty drives under the semi was the only “special effect” that was impossible in real life, in the first F&F. A civic dropped with its frame touching the ground isn’t low enough to fit under any trailer like that. And it still wasn’t CG. They raised the truck by a couple of inches to allow the civic to fit. You can see the spacers on the truck clearly if you are looking for it… Then we got the CG masterpiece that was 2F2F. Edited to add the name of the first movie. It helped with my point.

13:54 I'd also like to point out that the rolling shutter effect caused by the phone camera's relatively low performance electronic shutter is what makes the car to look like jelly. The vehicle parts move more uniformly in real life, but those images, referenced earlier in the video, are taken in slices of the CMOS at a time, meaning the top of an image is taken at a slightly different time to the bottom. This is why images look skewed if you take a picture of a fast moving object with a slow shutter!

[@Cloud30000]

Glass is not pliable enough to support the wave seen; the stress would shatter the window. That’s why plexiglass is used right near the speakers on the rear windows. The reason the rest of the image is not blurry is because current image stabilization software is designed to compensate for the movement and fill in the missing\blurry portions; older cameras did not do this, thus why most would assume it should be blurry. Cameras have become magical, but at the same time can guess wrong and present an invalid image in the process of enhancing\making it clean. This is actually similar to 4k and 8k AI upscaling, where the image is cleaner but the guessing needed may cause the wrong or unintended details to be added in the process. The better AI gets, the less you can the difference between what is real and what is not.

Fellow Physicist - that brake rotor is not copper. If it was, it would have heated homogeneously. That's some ferrous metal. You even explained HOW it's not copper, while claiming it's copper - it has VERY good thermal conductivity - you aren't getting a random cold spot from a continuous frictional heating - the whole thing would glow equally. Rolling shutter does NOT explain the cold spot.

Great episode... all of your best hosts in one video! That said... Angelina, what do you mean you've never seen a solid brake rotor? I happen to own two cars with solid brake rotors. One is older... a 1962 Triumph TR4 (note: 1956 Triumph TR3 was the 1st production sports car to use disk brakes). The other is a 1997 Land Rover Discovery. The solid rotors are no problem on the relatively lightweight sports car (2000 lb.) But they perform poorly on the SUV (4600 lb.), especially when towing. So I upgraded its front disks to slotted and drilled for better cooling, and use high performance brake pads.

The brake disc was a standard, old-skool, cast steel or cast iron disc. Certainly not copper, which you can easily tell from the very uneven heating caused by the warp in the disc - the thermal conductivity of copper would have heated the entire rotor much more evenly (the cold spot would not have been visible for long at all). These discs glow red hot often in high energy, high performance applications (such as racing), and the pads do catch fire if you come to rest with the disc this hot.

If you've ever tried to break tempered glass, it takes way more than a can being thumped down on it. (To be clear, something like a little piece of quartz sand or shard of hard ceramic stuck to the can's rim could be made to break it, or might be the cause of one breaking by accident, but under normal circumstances a thump from an aluminum can isn't going to do anything).

Spring-loaded center punch

Nice one Tony. I loved this video. More episodes like this please.

[@Oceanus_Rex]

4:00 Video is real. When you look at the 2nd camera view (overhead) you can see the guy's shadow on the Lambo.

In my physics class, our instructor told us the SI unit for momentum is kilogram meters per second. Obviously this is not a good term so we decided as a class that 1 KgM/s should be represented as Oomph. 2 KgM/s would be "2 Oomphs"

[@mnharlan7662]

Lye (sodium hydroxide) would absolutely do that to the window!

[@NullCreativityMusic]

Really digging the deepdive with the physics!!! Keep 'm coming please! Happy New Year Real Meachanics

[@Kryorgin]

3:50 is real , he did it again on a livestream later

[@sopcannon]

They did prove with physics it was real.

[@AntonioGGATX]

Yep. Also they didn’t note the tape on the road. Track runners that run relays do something similar. With the car within a speed range and knowing his own abilities, it’s like timing the take off on your relay leg.

15:46 We used to do mirror finishes like that in machine shop class in college. It's just about grinding with finer and finer wheels on a precision grinder. I had some mirror finished 123 blocks that when placed together wouldn't come apart. So it's 100% possible with a precision grinder.

when i was 14, my best friends dad had a 2500w speaker system in his living room. He had never taken the volume over like 20% because at that point, the whole house is getting tinnitus. one day, we got drunk and i convinced him to set it at 50%. i swear to god, the double glazed windows were wiggling. i had never seen glass wobble before, so it blew my mind. i had tinnitus for 3 days after.

[@Hoggaforfan]

Is a few videos of cars loosing their windows that way. A friend had a massive base, if he cranked it up, the picture on the other side of the wall fell down.

[@philipspigelmeyer959]

This was a GREAT video. Hope you guys do more like this.

[@berryrijnbeek5938]

Soda and cola , breaking the (safety!!!!) glass out of sight of the camera.... duhh....

[@NathanSeeley]

The way Tony's face lit up when bob suggested a mountain dew battery 🤣🤣🤣

[@Analog_Activites]

Bro looks like leonard from big bang thoery😂 and he's a physicist💀

[@KawaiiJessJ]

Sandro missed the perfect opportunity to give Tony the double thumbs up when he was getting technical lol

[@gilfish86]

They need someone to give Tony the thumbs up signal

[@RandyWSims]

This should be its own series. The physics of everyday stuff... and not everyday stuff. Now, I'm off to see if I can find more videos like this.

[@stevenroux4307]

This was the most interesting RMS to date! Keep it up yall 🎉

[@scott_larr]

Cheers Tony... I've always loved physics. Please do more like this!

[@anthonygenovese7578]

They're just like "yep yep, what he said. I heard him, but i'm not gonna even start to try and understand"

[@AcuteP4nda]

Sandro is high af in this and I love it 🤣

[@YaBoiJessy]

Well holy ducking didn’t expect this lol Mr.mathchecksout and Mr.Miata might need a series like SHEEEEEESH ❤😂😮

[@SirOtterman]

Please do more of these videos! Love the way he presents the info

[@darthkujo]

I enjoyed this episode. I started following the channel, and I love it.

[@Bluemon5ter]

This is an awesome topic. I was encouraged all the way. Thank you for sharing the knowledge.

[@neoanderson7]

Tony reminds me of a friend I use to have in High School. He later turned into a Mathematician. 🙂 Cool you came out from behind the camera.. Sandro and Steph are in this clip.. 🙂

[@bradseeker]

i appreciate how tony explained stuff with just enough detail that it was informative w/o killing the curiosity behind it. school teachers should take notes; they probably show his docs in class anyway

[@bradseeker]

like, bob's suggestion of mtn dew in a battery being met with "uh... yeah. yeah! yeah you can!" is truly the best moment an educator can provide. can't wait for a "the miata's father just designed a NEW BATTERY?" video

[@davidbryanttrucking]

Sondros face after he figures out that dude created a thermal crack in the window while the physicist tries to calculate what Sondro just said... Priceless. 😂😂😂

[@crothefool1651]

Please, make more content like this. Thank you, Tony.

[@gedas3419]

You guys should review Chebotarev's stunts

[@NeoBechstein]

soooo much thx for a scientific video! please do it again.

[@Alexanderaguilar]

Tony is real life Leonard Hofstadter! Love it! ❤

[@miguelm6997]

I don't know if the video matches the channel content so far. But I am loving it

[@cp368productions2]

As someone who lives 7 miles from a steep hill where multiple trucks have lost their brakes and have seen brakes catch fire. I know that first one can be very real.

[@geneeysmont9404]

Awesome content!!! More of this please! 👍

[@TwoTenTwice]

Its the real life Leonard Hofstadter 😂

[@drewk448]

Dude got really excited when asked if you could put Mt. Dew in a battery. Then the video cut. I wanted to hear that ramble. This dude is awesome.

[@rhubarbpie2027]

I really enjoy the fact that Tony got into the weeds when explaining the principles in these videos 😂
