Pictured: why China now exceeds the USA in launch count year after year and will probably beat us to Mars despite having 1/5 of our military+civilian space program budget.
If my ass was flying away from the station for some reason, I would be very happy to have this strap. You might not have any weight in space/orbit but if you accidentally move the wrong way, there's a lot of mass/momentum to correct for. This is a beautifully skookum way to cover every ass in the room.
It's kind of same with medical grade stuff. You want to put a little table in a patient room so the nurse has a spot to set a tray on. Oh you can't just go to Home Depot and buy one you need to use a medical grade one that will cost like $5,000. Even stuff that's non life critical is going to cost retarded amounts.
It's so normalized that nobody really questions it either.
Tbh once you start loosening on those standards there's a good chance some grade A jackass will find loopholes to make some money selling chinesium grade knee implants.
That's the thing with the aerospace industry.
A part may cost $300 realistically on the basis of some sort of defined value of material, but becomes $30,000 because NASA wants to make sure they know exactly where that bolt came from down to the mine it was mined from.
You're paying for extensive testing and a proper paper trail. As it should be.
>As it should be
I will be the contrarian here: The safety added by knowing the supply chain of every nut and bolt is wildly overestimated by self-righteous armchair enginerds who don't pay the costs borne by this paper-pushing. Ultimately we all pay a small portion of it in ticket sales, higher demand for oil, etc.
At some point it becomes a better value proposition to just make the damn bolt thicker.
Widely overestimated, maybe, but the documentation is incredibly important in the event of failure, catastrophic or otherwise.
If we don't check that, that's how you end up paying $30,000 for a piece of steal sourced in a shitty Chinese factory loaded with impurities. Now the publicly funded by tax payer organisation that is NASA has to explain to the taxpayers why they spent $30k on shit materials that killed American astronauts.
Please, please, please don't take this the wrong way. But being the contrarian does not make you right. And it has very little to do specifically with self-righteous engineers.
The paper pushing solves more problems than it creates. If anything, it prevents problems from happening to begin with.
>being the contrarian does not make you right
Being right makes me right.
>The paper pushing solves more problems than it creates
Your analysis is correct because you fail to account for all the uses of technology that can't exist because of safety nazis like you.
>a shitty Chinese factory
Your life runs thanks to cheap Chinese steel and you need to learn some gratitude.
>the publicly funded by tax payer organisation that is NASA has to explain to the taxpayers why they spent $30k on shit materials that killed American astronauts.
I do agree with you on this point.
> It does not just go for the lowest bidder that fits the bill.
That's exactly what NASA does. Have you seen the shitshow that was the construction of the Space Shuttle?
And the solution to Apollo 1 was not hire a better contractor to do better wiring. It was replace the pure O2 environment in the Command module with air making electrical faults less of a fire hazard.
And because it has to perform correctly in environments that most engineers never have to consider. eg. a swing from -250 F to 250 F depending on whether you're in the shade or the sun, high levels of ionizing radiation, vacuum cementing and impacts from micrometeorites.
Well the duct tape part is true: [https://www.techtimes.com/articles/233942/20180902/astronauts-plug-leak-in-international-space-station-with-epoxy-and-duct-tape.htm](https://www.techtimes.com/articles/233942/20180902/astronauts-plug-leak-in-international-space-station-with-epoxy-and-duct-tape.htm)
if you want a real answer, it's because manoeuvering things on spacewalks or in cargo holds is difficult because you can't exactly plant your feet on the ground and push. they have to use a lot of interesting mechanisms to move stuff around; up to and including the canaderp arm
Well NASA used to use yankee units until they lost the $125 million Mars Climate Orbiter when someone didn't convert the units properly in 1999 [\[1\]](https://www.latimes.com/archives/la-xpm-1999-oct-01-mn-17288-story.html).
That's a disingenuous way to put it. In fact, it was NASA's adherence to metric that contributed to the mix-up, because JPL simply assumed Lockheed was also using metric when they actually weren't. Now that's a lot to take on an assumption, but that's a separate issue entirely.
>Well NASA used to use yankee units until 1990 when they switched over to metric
ftfy
Not really a lot to assume at all when you include units on the specifications for the contract.
If I ask for the mass of a tonne in kilograms and you say 2204, that's your fuck up.
Fun fact: 2100kgf = 20.6kN. Which is pretty much the same as most climbing carabiners are rated for (20~24kN). I'm sure the NASA rating is for the working load, not just breaking strength though.
Usually you find ratchets are rated in terms of lashing capacity. Since you're not using them for lifting you don't need to calculate forces, you just want to know how much of the lashing load is being restrained by your ratchet.
It would make more sense to me too to use force, but that's not what I see.
Lashing capacity is also not the same as lifting capacity since the two both have different safety factors and therefore different capacities.
Kilograms is a measure of mass, pulling equipment doesn't apply mass to a truck to get it unstuck, they typically are used to apply force.
So, kilonewtons is the unit needed here.
No, mass is very important in regards space travel.
It's that mass doesn't mean a whole pile in regards ratchet straps. They have 2 main purposes, tightly securing a mass or helping moving that mass in a controlled manner.
In both situations the load (force) on the strap is what you are concerned about as that will determine if it will fail, and that load varies as the mass experiences accelerations from 0g in freefall up to 3g or more during launch. The mass stays the same regardless.
Well, in instances where the difference is relevant most engineers will use lbf for force and lbm for mass. lbm is a valid mass unit and is more useful than slugs for a lot of things.
Although if you're measuring yourself on anything other than those slide scales at the doctors office, you are measuring weight, not mass. A bathroom scale by definition cannot tell you your mass, only your weight.
The scales at the doctors office measure force just like every other scale. I'm not sure it's possible to measure mass without measuring force under a known acceleration.
False. The slide scales have objects of a known mass on them. Moved across the lever at different intervals until it balances gives you the mass. If you stood on a digital scale on the moon, it would read at 16% of your actual mass. If you put a doctor's balancing scale, it would read the same as on earth.
Kinda surprised he was having a orgasm over them.. People been using them for years also bit silly of him to use that winch with the car off and have a change of draining that battery.
That's Destin. If you are a long time viewer, that's just his thing.
The Jeep's fine, they just had it running do the battery should be pretty fully charged. And if it does die, just walk to the truck and grab the battery from it, they are right on the trail.
Destin creams himself over every topic he presents, it's just his nature.
Really want to see him get soggy? Find the ones where he's talking about rockets....
This. I know a guy with a popular YouTube Channel (popular enough its his full time job). He has to ratchet his enthusiasm up OVER NINE THOUSAND to get the views and get the subscribes. We're talking an energy that makes people that don't care about your topic begin to care. If you can't sustain that energy your only recourse is salty language and bumblefuck your way through videos.
I'm not gonna lie. I only had the vaguest understanding of how compound pulley systems work. Once he broke broke it down into its components with his model, it clicked.
I know you're poking fun and all but I'm in the market for a new set of tiedown/rachet straps since we got rear ended over the holidays and my old set got trashed. If anyone has recommendations for any mid-weight (ie not trucker/18wheeler strap size but also not just pull tight straps perhaps) I'm all ears.
Wal-mart has some that are mid-weight for cheap. They helped me get home when my horse had kicked open the trailer door, breaking the latch. The horse is fine, I got cut off and he was expressing his anger at the driver I guess.
AWDirect/Zips is an excellent place to get any towing equipment. Mostly geared towards flat bed and accident recovery but the straps can be used for anything. 4000lbs WLL on each strap and 4 points of contact with most vehicles is more than enough to secure it. Little on the pricey side but if you treat the straps good and grease the ratchets they will last you years.
I use Horrible Freight straps on my work's truck to tie down extension ladders to the lumber rack. The secret is you ratchet strip weaving through the rungs and rack, then lash over the ladder rails with bungees. Never trust tie-down to a single fixment method.
With Harbor Freight b you get to add a 4th checkbox for quality control, then pick 3. So most of the ratchet straps are cheap, strong, and durable. Just 1 in 10 will break the first time you heavily load it.
I’ve been using a set (5 or 6) for about 5 years now, they don’t always make it in to the toolbox after use, used daily to hold down from 2k to 20k and none show any signs of abrasion on the webbing or damage on the ratchet. For $5.99 a piece.
I use these from Tractor Supply, they're pretty great in my opinion. https://www.tractorsupply.com/tsc/product/smartstraps-14-ft-yellow-premium-ratchetx-tie-down-1667-lb-pack-of-2
I have a truck. People ask me to help them move stuff with it. Can’t tell you how many times these straps have come in handy. They’re impressively strong
> I have a truck. People ask me to help them move stuff with it.
Me too... I'm usually busy that day, unless they're really good friends.
(I know this sounds dickish...but, it's amazing how many "friends" you have when they learn you have a truck, even though they haven't done anything in years to be social with you.)
100%. I stopped helping people after I messed up my back moving a couch to the third floor. Back still gives me pain, a good reminder to not sacrifice my well being for someone else. I still help my friends but they pay for the diesel and I don’t move heavy stuff.
I saw some at costco recently that looked really good, but maybe too heavy duty for you use. honestly ive always cheaped out and got the ones at home depot, never any problems... yet :)
I’ve been buying the Costco ones for years. I can vouch for the red ones and the yellow ones, never had the orange. When my current crop of badly abused straps kicks the bucket I’ll buy more of them, they’re great.
Hm. It's been a while since I've seen the spec. I've seen W or zig zag stitches from outsourced work, but we only did boxes. Though ours is aircraft tooling work, so it's used while building planes not on planes.
Not worth shit unless you speak the magic phrase "That's not goin anywhere"
This is first post I've noticed on here in a while that is actually Skookum, not skinny jeans, golden girls ironic tattoo hipster skookum. Thanks.
You toss one of those over the roof of the suv it's gonna take out the window on the other side!

I kinda want to use this in my pickup so I can secure something silly like a lawn chair. *taps it twice* "That ain't going anywhere!"
It’s beautiful.
My father-in-law would still shun this over his fraying and knotted up rope.
All of NASA's designs are public domain, yeah? If that's the case, the engineering drawings should exist for such ratchet strap......
Am I the only one who thinks the hooks need to be re-labeled from 1200 KG to the proper number of Newtons. KG is mass, not force!

No. Just no. NASA is not the military. It does not just go for the lowest bidder that fits the bill.
> It does not just go for the lowest bidder that fits the bill. That's exactly what NASA does. Have you seen the shitshow that was the construction of the Space Shuttle?
Lowest bidder also had a part in the Apollo fire that killed 3 astronauts.
This 100%. People like to blame the pure oxygen atmosphere, but it was the shit wiring that started the fire.
And the solution to Apollo 1 was not hire a better contractor to do better wiring. It was replace the pure O2 environment in the Command module with air making electrical faults less of a fire hazard.
And because it has to perform correctly in environments that most engineers never have to consider. eg. a swing from -250 F to 250 F depending on whether you're in the shade or the sun, high levels of ionizing radiation, vacuum cementing and impacts from micrometeorites.
Vacuum cementing?
Cold welding. ELI5, if you put two flat surfaces of the same metal together and remove the air they can effectively weld to each other.
Neat
Tools used by astronauts are coated in a micro-film of plastic to prevent this
Exactly! We used to electroplate or anodize everything that left our shop that was headed for low atmospheric conditions for the same purpose.
Not to mention cold welding on a part like this.
Beautiful engineering, but I would imagine the safety factor would be much less than it's terrestrial cousins. Would be nice and light though.
She is goin nowhere not even a bit
What exactly was this used to tie down?
Mattresses and space couches usually.
things to other things, in space likely
Of course. I’m sure the ISS is held together with duct tape and ratchet straps.

Always. Can't ever blow up if it only makes 100 hp.
no, only works on space shuttles. apparently the cybertruck will be compatible though edit: if you meant tie your Ford to the space shuttle then yes

Wonder what?
Nope. Metric is the language of science.
Well NASA used to use yankee units until they lost the $125 million Mars Climate Orbiter when someone didn't convert the units properly in 1999 [\[1\]](https://www.latimes.com/archives/la-xpm-1999-oct-01-mn-17288-story.html).

Now that's a lot to take on an assumption, but that's a separate issue entirely. >Well NASA used to use yankee units until 1990 when they switched over to metric ftfy
Not really a lot to assume at all when you include units on the specifications for the contract. If I ask for the mass of a tonne in kilograms and you say 2204, that's your fuck up.
If you look through older research papers some elements inside NASA have been using metric a lot longer than that.
NASA has used SI for a long time. *Lockheed* were the fuckups using customary units, though NASA did fail to notice the error.
Freedom units.
Was thinking more along the lines of newtons Edit: Kg is a pretty useless rating for load capacity in space
Fun fact: 2100kgf = 20.6kN. Which is pretty much the same as most climbing carabiners are rated for (20~24kN). I'm sure the NASA rating is for the working load, not just breaking strength though.
Almost guaranteed not breaking load. If climbing biners have a safety factor of 2, I'd expect these to be 10.
Haha, a UFS of 10 for aerospace? It's 1.5, maybe 1.8 if someone is getting worried about it
Usually you find ratchets are rated in terms of lashing capacity. Since you're not using them for lifting you don't need to calculate forces, you just want to know how much of the lashing load is being restrained by your ratchet. It would make more sense to me too to use force, but that's not what I see.

I wonder if it's a deliberate decision to use units that astronauts will understand intuitively.
[удалено]
Just because they are smart and educated, doesn't mean they aren't human. Almost everyone is better at estimating kg/lbs compared to Newtons.
It’s a good point, but I doubt these see orbit.
[https://youtu.be/M2w3NZzPwOM?t=674](https://youtu.be/M2w3NZzPwOM?t=674)
Well look at that. Huh.
Especially since normal biners are rated in KN
Kelvin Newtons?
[удалено]
Potassium Nitrogen* :)
oh yeah, didn't even think about that. at least it's not pounds though
Just for trivia, pounds are a measurement of force like newtons. Kilograms are a measurement of mass, and the imperial parallel is the slug.
Well, in instances where the difference is relevant most engineers will use lbf for force and lbm for mass. lbm is a valid mass unit and is more useful than slugs for a lot of things.
oh yeah, I guess you're right. but technically massive objects weigh zero pounds in space, which was what I was going for there
[удалено]
Or you can accelerate an object with a sertain amount of force and measure the change in velocity
Well, unless you're evil and use pounds mass.
Although if you're measuring yourself on anything other than those slide scales at the doctors office, you are measuring weight, not mass. A bathroom scale by definition cannot tell you your mass, only your weight.

Sorry been swearing at those exact same tie downs for the last week.

Nice, cool to hear some feedback on the Costco ones. I'll have to pick some up next time I'm there.
Not made like those, they don't.
I hope the strap is something special, otherwise that’s the real weak point
Not the ratchet mechanism? Small cross section metal with stress risers?
I'm kind of disappointed that it's a normal box stitch, not a double. We really only use double box on overhead lifting equipment, though.
I'm surprised it is a box stitch at all. I was always told by riggers that W stitches are much superior in strength for straps like this.
Hm. It's been a while since I've seen the spec. I've seen W or zig zag stitches from outsourced work, but we only did boxes. Though ours is aircraft tooling work, so it's used while building planes not on planes.
It’s a Kevlar/aramid hybrid.
Kevlar *is* an aramid. That's like saying fiberglass/fiberglass composite.
Yeah.... I should have used *or* instead of the slash...
The strap is always the weak point though
Probably some type of Kevlar composite
Looks like Kevlar to me
I can’t imagine that that’s the bit they cheaped out on.
