Pile Of Garbage posted:Things that had nuclear warhead options in the Cold War: Phanatic posted:The raw W54 warhead was that small, but the smallest “backpack” it was ever deployed in weighed 150lbs and definitely wouldn’t have fit into an airplane overhead. Pile Of Garbage posted:Can't find a good reference sorry. Let's call that one bullshit on my part! I can't recall any nuclear MANPAD systems but you did forget about the M-29 "Davy Crockett" nuclear recoilless rifle:   It had a 2-mile maximum range and a yield of only 20 tons (0.02kt). It was quite inaccurate, so its most tactically useful effect would have been the radiation blast, which would have instantly killed any unshielded troops within about a 500-foot radius. It would probably also be fairly effective against helicopters and light aircraft at low altitudes. It could be carried in three backpacks or fired from the back of a jeep

Harik posted:They're utterly nuts. Weren't those the ones that you could launch at the same time you fired a .45 and it would be a few hundred foot airborne before the bullet left the barrel? I haven't heard that specific factoid but the math doesn't check out. A .45 has a muzzle velocity of 830 feet per second, so with a 5-inch barrel the bullet accelerates at roughly 26,000g and takes 1 millisecond to leave the barrel. The Sprint missile's overall acceleration was 100g, meaning that in 0.001s it would only have traveled half a millimeter. Even going by reports that "the missile was supersonic by the time it left its silo," meaning it reached at least 1125 feet per second in its 27-foot length, exiting the silo in under 48 milliseconds, that's still only 730g in the initial ejection phase. The bullet would be 40 feet away at that point. It would be totally accurate to say that by the time the missile left the silo it was travelling faster than a .45, though. e: and it's been a while since I've done quadratic equations, but I think I've worked out that if you were standing beside the underground missile silo with the gun beside your head and fired it upwards at the same moment the missile was launched, the tail of the missile would have passed the bullet after slightly less than 1/10 of a second, 80 feet above the ground.

madeintaipei posted:Because the next five pages of this thread are going to devolve into a huuuge argument as to whether or not Will Smith's ad-libbed line in Independence Day is "Welcome to Earth" or "Welcome to Earf" after punching the alien into submission. I wanna say it's rule 36, paragraph 5, of the internet. (It's a really stupid Reddit joke) It's "earth," always has been, you can look up the scene to verify this in 10 seconds, and the "earf" side is racist because it's implying that Will Smith must speak AAVE because he's black. i hope this has cleared up the argument

Enoch Root posted:Does anybody know what type of plane this is? I want to send it to a friend of mine who is a commercial pilot and I'd like to pretend I know at least something of aviation. It is a Boeing 757. We know it is a Boeing because the cockpit windows are pointy at the back where Airbuses are all square. 757s can be hard to tell apart from the longer 737s, but there are a few tells: - there are four wheels on each set of main gear (737s have two) - the vertical stabilizer's leading edge is one straight line (the 737 has an extension at the base) - the nose gear is mounted further back than on the 737 (this is hard to tell in the video but you can detect it at the end) This one specifically appears to be a 757-300 because it has four doors on the side of the fuselage (the -200 model has three).

PHIZ KALIFA posted:OSHA thread, I have a question. Let's say there's a hill, 200 yards wide by 300 yards long. The middle rises to a 60' mound, we can assume a uniform shape, roughly triangular pyramidal in design. How long would it take an average construction team with modern equipment to excavate that area, to a depth of 60'? some back-of-the-envelope calculations suggest that you could move that much earth with a 30-kiloton nuclear device buried about 350 feet under the surface. that isn't exactly the shape of the excavation you need, but that's the kind of energy release involved. perhaps three ten-kiloton devices buried to the desired excavation depth in a chain 100 yards apart? it would be a lot faster than using construction equipment and you said you don't care about what's underneath so

My uncle flies waterbombers in Canada and his path, fwiw, was: join the RCAF -> basic pilot training -> rose to captain as a navigator on the CP-140 -> got sick of the military and applied for a discharge -> live on our couch for six months while building up hours to be a commercial pilot -> bush pilot in central america and northern canada for many years -> hired by the OMNR to fly the CL-415. It doesn't seem like a particularly quick and easy career change

worth noting that the rates of youth violence have almost perfectly tracked the utilization of of leaded gasoline with a 15-year lag. the phaseout started in the mid-70s and by 1990 youth violence was on the decline, contrary to all predictions at the time. it's now at a historic (post-ww2) low and so is airborne lead concentration. cops a re already murderous psychopaths, of course, but the lead exposure probably doesn't help

Note that even if you give him the benefit of the doubt on the the catch-all 14 CFR § 91.13 "careless or reckless operation" rule, Jerry is still violating the 91.119 minimum safe altitude rule, which says that you must be 1000 feet above the nearest obstacle within 2000 feet in any congested area. He's definitely not 1000 feet above the Bay Bridge towers. e: his altimeter actually reads ~500 feet when he starts that insane 60-degree banked turn. The Bay Bridge towers are 520 feet tall.

Lazyhound posted:just gonna take a sharp bank with an open drink by the instrument panel, what could go wrong  A properly coordinated banked turn is a positive-G maneuver and the apparent gravity vector remains aligned with the aircraft. A level 60-degree banked turn pulls 2G, and he was climbing slightly so he was a little above that. The drink would remain in the cup.The sensation of multiple Gs straight downwards, which in this case would feel like gravity just suddenly doubled, is pretty bizarre at first, so that's probably why his passengers start screaming "oh my god" as he rolls in.

Yep it's called a rolling shutter artifact. In this case, you can tell that the CCD reads out from the top to the bottom, line by line; by the time the frame is done capturing the train has moved forwards, so the bottom slides a little bit in front of the top, and it looks like it's leaning backwards. Most cheap image sensors, like you'd have in a security camera or cell phone, do this. More expensive sensors like those in a digital SLR tend to read the whole frame at once to eliminate that artifact. Fun fact: this effect is why animators distort cars' wheels into ellipses, and generally lean the whole car forwards, as a visual shorthand for "going fast."  Obviously cars don't look like that in real life no matter how fast they're going. But if you're a photojournalist in the 1930s, and you have a camera with a travelling-slit shutter, then you get the exact same effect. The film is exposed over a brief period of time -- from the bottom up, due to the curtain design of most camera shutters at the time, rather than top-down like most modern image sensors -- so the bottom parts of the scene are recorded first, and fast-moving objects look like they're leaning forwards. Animators looking at photographic/filmed references of fast cars picked up on the effect and now it's just part of our shared visual language.

"Why should I be forced to pay for health insurance when I'm healthy and don't need it?" He was in the army  Anyway re. the fire, I'm sure that if Tennessee wants to stay in their libertarian hell world of paying no taxes and hiring private fire departments, any actuary could quickly come up with a figure to charge for on-the-spot firefighting that would compensate for the lost $75 up front. Ten thousand dollars? Twenty? Still cheaper than a new house.

Phanatic posted:FWIW, the town changed things so that their department will respond to all calls within 5 miles of the city limits. If it turns out you don't have the subscription and they need to put your house out, they will, but it'll cost $3500: That seems fair to me if you live in a place where a tax-funded municipal fire department wouldn't work and you choose not to buy the "insurance"/subscription. At 75 dollars a year, the $3500 fee covers 47 years of fire service, and one fire call per ~50 years per house sounds like it's in the right ballpark. Sounds like they did hire an actuary after all!
