Well it also covers all of the sub-systems on the aircraft as well, from countermeasures to communications down to how to evacuate the aircraft toilet waste.
The information in that manual is probably spread over the domain of 100's of people all performing different roles. I don't think their is any expectation that one single human would read the entirety.
Kinda like your car manual or university textbook. I've never read mine from cover to cover, but it is a useful reference sometimes. Particularly in the case of Air Force One where I doubt an internet search covers most troubleshooting requirements.
Seems novel in that they are combining the best of current rotary atomizers and electrostatic guns, and removing the need for compressed air.
If you look at current electrostatic guns, they mostly seem to use compressed air to atomize the paint. Rotary atomizers still use air to direct the paint to the surface.
So they get better transfer efficiency through electrostatics, and the rotary atomizer part probably allows them to use paints with lower VOCs further reducing emissions.
That said it does look like there already exists rotary atomizers that also use electrostatics. But also still use air.
In terms of a general statement, its a bit misleading to state that sintered metal gears retain the improved strength of traditional metal gears. They are a lot stronger than plastic gears, but in the majority of cases (particularly in hand power tools), they do not have the strength of traditional machined gears.
Read the sentence immediately preceding the one you quoted, her reasoning is to "bask in a glorious downhill". She needs the full width of the road to give a larger margin of error due to speed and to maximize her enjoyment.
A simple considerate solution would be to slow down and pull over.
The crux of the issue is that people of every persuasion, be it cyclist or driver, would never consider inconveniencing themselves or sacrificing their enjoyment for the good of others. i.e. they are selfish.
I cycle and also occasionally tow (which puts me in the group of annoying slow road users). My frustration with these type of articles is they only ever ask for the road to be shared, but do not share the road themselves. As a slower road user you should also be considerate of other road users. An example would be when towing and driving at a more sedate pace, when it comes to passing lanes - SLOW DOWN - to allow the pile up of cars behind you to pass. However most people simply maintain their speed, ignorant of the building frustration behind them. By slowing down you might add 30seconds to your travel time, but give 10-20 people back minutes to their travel time (a net win for society!).
In this case if the cyclist periodically slowed down and moved to the shoulder when going downhill (or in general), the pile up of cars and frustration might be mitigated.
"Through my eyeglass-mounted mirror, I watch cars inevitably pile up behind me. When the terrain flattens out and I move back to the shoulder, a stream of cars pass me."
I'd argue that the pool noodle may have unintended consequences, and will most likely increase road rage. It seems to scream EMPOWERMENT ("taking back the road"), but I think it leans more towards SELFISH BITCH.
We don't have the luxury of McMaster Carr here, but a quick search suggests that they have history and expertise in supplying engineering equipment which explains why they are so much better than Amazon.
It does seem like large tech companies tend to take less than stellar attempts into these sort of areas because they don't hire people with the appropriate expertise.
That said I appreciate the fact they don't for a number of reasons as it's definitely something I wouldn't want Amazon to step into and stomp the competitors in the field.
Yeah wire gauge fasteners is definitely weird, not something I've used, but from a quick look they exist, although I'm not sure if they get much use.
Castle nuts are a bit of an oddity too. Id assume your friend is possibly using them for trailer bearing retainers or possibly some really old suspension items. Not even sure there is really even a specification the ones available here seem to adhere to.
They are something I've generally gone out of my way to engineer out of a lot of applications as there is better options available.
Stainless I would argue belongs in material not in grade and class as these are different attributes. You can get grade 10.9 bolts in stainless, black, zinc plated and possibly in other materials and finishes. If it doesn't specify the type of stainless steel the safest thing to assume it's a low quality material which doesn't conform to any specific specification or at least lacks the appropriate accompanying paperwork.
I.e. I'll select a grade/class based on the mechanical properties I require, and the material will be selected taking into mind the environment the fastener is going into, any possible material incompatibilities there might be, i.e. don't want to accidentally build a battery, or select materials which gall together.
Honestly I think search in this area is actually extremely difficult due to all the inconsistent standards, specifications as well as random proprietary fasteners that exist.
I find that websites that sort by category to be better in this space, but that also assumes that you know what you want.
Fastener classification does tend to be a bit vague at best. Generally I find generic terms are used for low grade products, and often for products which you may struggle to find proper material certs for. Fine for general use home use, but no good in industrial engineering applications.
Id imagine that the problem is that software engineers don't understand hardware engineering, and it's actually not a space where a lot of good resources exist. I.e. without a little bit of familiarity with material science and industry, it's not just something you can easily google. You need an engineer familiar with the fastener industry if you want a chance for getting a decent system of classifications.
Also from a metric country, things like number and wire gauges are odd to me as well as I only occasionally have to deal with them.
If you are looking for fasteners for specific industrial use then I'd assume you would have the expertise to select the appropriate fastener or some internal engineering specification to follow. You don't just buy something from the scientific bolt category on Amazon. You may also require material certificates etc, which I don't believe is something these online options typically offer, though I may be wrong.
The difference between zinc plated fasteners and hot dip galvanised fasteners is actually quite significant. Zinc is usually around the 20micron thickness possibly less, whilst galvanised is usually >60micron usually quite a bit more.
The process for applying the coatings as well as the end use of fasteners with the two coatings is also quite different.
By not marketing it as a replacement for the 7, Apple has managed to significantly bump the price of the device with barely anyone the wiser. Anyone hazard a guess at the increase in apples profit margin on the X. The price appears to have gone up significantly, for a comparatively small increase in BOM cost.
Even if you question their design decisions, it's hard to fault their product strategy
The HiMAT basically demonstrated this. Unfortunately there doesn't seem to be much information online about the program, however some books I've read note that the program was a success.
Rudimentary fuzzy logic in this kind of platform should be able to defeat a human pilot regardless of the pilots cunning/unpredictability/other human aspects which movies trump as superior human features. But, practical requirements such as range, payload, loiter time, pork barrelling may mean that the platform is otherwise compromised.
Additionally in an era where things such as airborne lasers are becoming a reality, the whole meta may completely change.
