is this Phenol, the same one used for some "skin peeling" treatments people do on their faces! nowadays? People really go a long way to find painful new ways to die...
That is quite the accidental endorsement 😂 Also, the wind noises from the camera make it sound like the camera was screaming with joy like on a roller coaster: "whoOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOooooooooooooooOOEOEOEOEOEEEEEEEEEE!!!!"
I want to see you get an x-ray machine. Maybe you could even team up with a few other science/maker RU-vidrs to build a CT machine. It would let you see the internal structure of your grains without having to dissect them. It could turn into a lot of content for posting. Very lucrative!
Bisphenol-A synthesis: Replace acetone with fluorenone, replace epichlorohydrin with propargyl chloride. Behold a reactive monomer, C31H22O2, mw = 426.514, 87.3 wt-% carbon, thermal cure. B-stage it, powder it, load it with hollow refractory silica or ceramic microbubbles, near 60 vol-%. Press to form while finishing thermal cure. Near zero thermal conductivity, low density. Sloughing molten silicate protects underlying carbon against oxidation. Adding zirconia fiber makes it even better re brittle failure.
Why the hell do you have a useless and clickbaity arrow in the thumbnail pointing to the ONLY THING in the thumbnail? Clickbait in thumbnails such. And so do channels who prioritize them. Oh well, another channel to block.
you cut this in your garage, then your garage is coverd in dust, then you vacuum clean the dust... the finest particules pass through the vacuum air filter then goes to your lungs. Then it shorten the life of one of the precious brains of the humanity. And we dont want that. Next time, go cut this in the house of stuppid dude (just kidding) DONT cut hasardous material or do it with special equipement with a filter and a vacum that suck things outside !
I love how Joe is “learning” with brilliant outside on his laptop while wearing sunglasses, then procedes to tell us WE can’t see it when I’m pretty sure he definitely can’t see it lol😂
Do chemical names count as big words for making you sound smart? I always thought that they made you sound like someone with dysphagia spilling a soup of one and two syllable nonsense words.
Maybe you need a simple analysis tool that checks all the connections are in place. ReadyToLaunch and return a green or red. Checks the values are where they should be. As you go higher with more cost then you might be glad you have this simple analyser. Good video. Keep going, you'll get there.
Is it worth simulating the glue and bumpy lumpy surface? Perhaps someone can make you a camera mount and design a groove in your rocket tube to fit the cable too. Total guess that imperfect surface might be affected by fluid dynamics at supersonic speed and above. A strong fluttering pocket of fluid could possibly move the rocker or damage it. Maybe even make it's fuel usage above calculation.
The only reason why heat shield tiles fell off was because the tiles got loose and flew off by the force of ionizing heat. Thus it melted the stainless 301 steel. Just like a plasma torch cutting through metal. Air composed of nitrogen and oxygen enough friction will create intense plasma heat that can even melt steel! 😳 🤯
I'm gonna help you out here, cos you've got chronic Mansplainer & I feel sorry for you. The Norwegians, a bunch of damn socialists, gave CFD away for free 20 yrs ago. Then they made FreeCAD, some one said "Right, then!', & added them into the one thing. There's a guy called Bernd who explains it so very well. On YoutTube. If you know Python then you can parameterise & automate. Prob you need Linux or the WSL. Also, there's this thing the kids are doing, called 'mathematics', that will let you figure the side force out for yourself, versus your inputs. & oh. If speeding is the most dangerous thing you do, that explains the shirts. Oh. & oh. ITAR & all that other weird stuff, abortion & whatnot, no one else cares.
I worked with Phenolic resins for over thirty years, and they are reasonably safe toe use. Sure, formaldehyde can be emitted, however this may be scavenged with additives. Base-cured types are less brittle and don't need the unpleasant acid catalysts that acid-cured types have, but are slower curing. Once cured they are very stable.. The solvents used to make the resin more water-tolerant can be problematic however.
Should we ever use the term 'degree' in connection to Fahrenheit's (or rather Romer's) scale? I reckon degrees are strictly connected with Kelvin's and Celsius' (another historical misnomer) scales.
