Why the Olympic monobob event is only for women

spawnflagger says...

nothing new... the Russians have been sending burly "women" to the Olympics for decades.

I think they could take this monobob 1 step further, make it purely a skill sport by adding weight such that the combined pilot+sled weight is the same for everyone, and use a railgun-style launcher (tech existed for rollercoasters for years) that sends everyone at the same speed. That could even be a mixed-sex sport, like Nascar.

Sadly some transgender will enter and win hands down.

Democrat voter has strong message for Biden

newtboy says...

This is not a Democrat any more than Diamond and Silk. This is a paid political actor. Far from the first Fox put on the air pretending to be a Democrat.
Every “complaint” is a dishonest Right wing talking point not based in reality.

Biden allowed trans women in sports!? Exactly how did Biden do that? Precisely when? Exactly what was his personal act that suddenly allowed that when it was disallowed before? Odd, since trans women have publicly participated since 75 and the Olympics allowed them since 2004.

Afghanistan….as mentioned above, set up by Trump and the Taliban after Trump had thousands of Taliban fighters released from prison that immediately attacked Afghanistan. There was no other way that would go but a faster, more chaotic withdrawal earlier like Trump agreed to (but made no efforts to plan).

Critical Race Theory?! Of course, this Republican shill misrepresents what it is and where it’s taught. He doesn’t like how racial sensitivity divides us, but has no issue with the Republican laws being enacted that outlaw making white people feel uncomfortable. I defy him to define critical race theory and tell me where children are being taught that class. They can’t.
Next he tries the 2020 Trump position, Covid isn’t dangerous, there shouldn’t be ANY pandemic response, and all the dead are now Biden’s fault because he did something to mitigate damages and slow the spread.

Next he claims that Democrats have moved so far LEFT that they aren’t recognizable, but in reality the Democrats have moved far to the right for decades and the right has taken a rocket sled into far far FAR right wing insanity…..so far that they want to befriend communist/socialist Russia to spite the American leftists. WHAT!?

The fact that another paid political actor is willing to act a fool on Fox and lie through his teeth means nothing more than more evidence that they’re blatant liars and their audience are brain dead slugs that couldn’t critically think their way out of a wet paper bag. I’m looking at you, @bobknight33…trying the same old dishonest #walkaway nonsense that failed before. (Because they were all stock photos and paid actors)

Can Spinlaunch throw rockets into space?

maestro156 says...

Yeah, 20000ft is roughly 6km. The air density is about 1/2 but from what I can determine that doesn't equal 1/2 air resistance, but something more like 90-95% air resistance of sea level.

Having said that, I haven't studied aerospace engineering, so I might be getting the details wrong.

There are definitely some minor advantages to building on a mountainside, but I don't think they outweigh logistical difficulties under normal circumstances.

The idea has a good bit of scifi (and probably scientific) history behind it though. I believe Heinlein used a railgun cargo launcher from the moon in Moon is a Harsh Mistress and a mountainside sled rocket in one of his earlier books.

Project Rho is a great resource for hard scifi and rocketry research for writers. http://www.projectrho.com/public_html/rocket/surfaceorbit.php is the link to a page that discusses maglev, railguns and rocketsleds.

I’m thinking Mt Chimborazo in Ecuador…at over 20000 ft, it’s peak it the farthest from the center of the earth (while not being the highest above sea level thanks to the equatorial bulge).
Sure, it doesn’t remove air resistance or friction, but halving it, even cutting it by 1/3 is a massive leap in efficiency and negates much of the extreme engineering and materials needed to overcome the friction….plus, as you mentioned, there’s the rotational speed advantage from launching on the equator vs Florida.
Also, while extremely minor, there’s also a slight reduction in gravitational pull at those heights. A joule saved is a joule earned!

Rocket Sled Impact Test In Slow-Motion

StukaFox says...

That's correct, but I have to wonder the practicality of this test given that the whole point was to show the 'physics package' (the part that goes 'fuckin' BOOM!') wouldn't be obliterated in the event the Chinese blast it with a rocket sled.

Didn't they say it was inert?

mxxcon says...

It got smashed the fuck up! That will teach the Russkies if they mess with America, we will send more rocket sleds against their inert nuclear weapons!
USA!

It's not clear to me what this says about our Nuclear Weapon Stockpile. What was in that inert dummy nosecone, and how did it do?
