    As a Engineer at the aeronautical industry I can say to you that there are REALLY strict rules on what is considered to be "the loads expected" on a airplane. Yes, the factor of safety can be considered "small", but the "expected loads" is actually waaaaaay higher than any regular operational load. The level of safety of a airplane is State of The Art in the engineering world. :) Fly safe, fly relaxed.

    That makes sense, because the airplane can easily increase the load on the fuselage and wings during an emergency event. It didn't make sense that you could have such a small safety factor and still have such insanely high survivability rates otherwise.

    2:14 As a structural engineer, I loved this entire segment. And I had heard of the the super low factor of safety of aircraft, but I believe it's more like 1.5. While in spaceflight, it routine gets down to below 1.25, or even 1.1 or lower, depending on how much that extra design capacity affects the weight and how variable the loads are. Modern structural design mostly uses LRFD design, verse the ASD (Allowable Stress Design) being discussed with all of these factors of safety. FoS are easy to understand and implement (FS=5, *BAM,* you're much safer), but miss a lot of nuance is the statistical nature of the _maximum anticipated load_ that you expect your system to have to support/resist. In Load and Resistance Factor Design (LRFD), you apply a factor to various applied loads, like wind, earthquake, self weight, snow and live loads, based on how likely they are to occur simultaneously (1.2D+1.0E+0.2S), and you also apply a different factor to the capacity side of things, based on how variable the type of fabrication is for that type of member (rolled steel = 0.9, welded connections = 0.75, brittle concrete = 0.65). Taken together, the Load Factors and the Resistance Factors are intended to provided a 1:10,000 chance of failure of any given member experiencing its maximum design load.

    I'm also pretty sure the standard safety factor for most commercial aircraft components is 1.5, and the factor for the pressurized fuselage is 2. Safety factors as low as 1.2 tend to apply to components like landing gear - which are obviously still critical but not somewhere where failure will likely result in serious injury.

  • @danielm2549

    Wren's understanding of safety factor of airplanes was far off. While yes, the safety factor of airplanes are typically 1.5, not 1.2 mind you, planes are designed to actually hold up to 2-4 times their max gross weight, PLUS the actual safety factor on top of that. Although their landing gear probably couldn't, their wings can due to increased weight in turns and possible emergency situations.

    As a former lift/elevator engineer, a lift made for 10 people cannot lift 100. It will start sliding downwards because a lack of friction between the belts/ropes and the motor wheel. The safeties will catch you though, but it won't be pleasant and getting you out will be an absolute pain if you've gone down far enough. It will most likely start sliding around 15 isch depending on the lift, individual weights etc.

The fact that she was married to Pierre Curie and that she had a French citizenship doesn't make her less Polish, as she was born and raised in Poland. Her last name Skłodowska should always be remebered as it was her real name and Curie was taken by her as a way to connect to the French science enviroment, besides of course being connected with her husband.

    I was wondering if maybe I didn't understand scattering on some fundamental level. What I think he means is that the light can only be absorbed when it strikes the molecule at one of its fundamental frequencies, and the electron is sent to a higher excitation state (think: spectroscopy). But really, Rayleigh Scattering is not absorbing, but kind of deflecting or siphoning some of the energy from the incident light.

    My favorite facts were that arctica means "bears" and antarctica means "no bears." I have known these terms since I was in elementary school, but no one ever told me what they meant or where they came from and I never bothered to look that up. But it was also pretty cool to learn about the "safety factor," since I assumed there must be such a thing, but I had no idea what it was called or what values to expect in the usual cases.

That's loading it 20% above the absolute maximum, then subjecting it to the worst possible in-flight conditions the aircraft will ever encounter, and no airline would ever fly in- think loop-the-loops in a hurricane- and it won't break. That's pretty dang impressive.

    ... and every second in the air gives you fos "for free", because like 20-50% of the weight of the plane is fuel. But the thing that was helpful for my mind, is that you can break almost every system, and the plane will still be flying. Typical example is that 4 engine plane will survive with 1 engine left. So its "layman's fos" is like 4+ - if you can survive with 1/4 of the things that make you fly. And now you can think about max load on top of that and the worst possible weather conditions.

    In response to Wren's comments about the factor of safety of airplanes, it has everything to do with the material used. Aircraft metal is made to a much higher standard than the steel used in elevators and buildings (big part of why it's called aircraft aluminum or aircraft metal) and when the material is much more consistent the factor of safety doesn't need to be so high.

    Sorry the Factor of Safety part is wrong. And Wikipedia is partially wrong. The factor of safety accounts for uncertainties in the design, loads, material, manufacturing, environmental conditions... There is a misconception in that engineers calculate strength. They don't. They actually estimate strength with math and other means. Aircrafts have safety factors of at least 1.5 for most parts, but rarely exceeding 2.0. Also different factors of safety for different uncertainties are layered on top of each other (mostly by multiplication). A Factor of Safety can be decreased by increasing certainty. For example: more complicated math in the estimation process, strength tests (the best part of engineering), quality control during production...

    To expand a little further on the safety factor (SF). Language and definitions differ between industries and areas. In general the highest load that can be reasonable expected during operation is the limit load. Based on standards and regulations (where they apply) and experience (where they don't) a SF or a set of SFs is defined. Limit load times SFs gives ultimate load. The design is based on the ultimate load. To exceed the limit load "because there's a safety factor involved" is wantonly negligent and if the justice system works as intended you go to prison. To suggest otherwise is incitement. I have seen regulations that state: You may apply a SF of 2.5 if you don't test the structure, but 2.0 if you test to limit load or 1.5 if you test to ultimate failure. The value of the SF may depend on the importance of the structure or the condition of the test. Extreme cold or extreme heat or both, maybe 90% humidity thrown in for good measure or you must use an intentionally degraded test subject. To select the appropriate safety factor is incredibly complex. To reason that it gives you a pass for misuse, well I made that point earlier.
