Below is a portion of an AI answer:
"The numerical designations for fighter planes follow a specific system used by the U.S. military. The first letter in the designation, such as "F" for Fighter, indicates the basic mission of the aircraft. The number that follows is the design number, which is...
Weren't the northern arcs ruled out as that would have put the plane where it could have been observed by radar, or observed visually if flying low to avoid radar, or observed visually by other aircraft that might be in the area?
The southern arcs were in the middle of nowhere where there is no...
Not mentioned in this forum thread yet. The helicopter pilots were wearing NVG - Night Vision Goggles. Doesn't this result in low peripheral vision, and what is called a 'tunnel effect'?
The location of any "hot spots" will vary with the location and size of the load (crucible) each time you place it in the microwave as the load affects the standing wave in the chamber. Food does not conduct heat well. Food is turned in microwaves so the food cooks evenly despite hot spots. Your...
I twice have bought older HP and Tek catalogs off of eBay as an aid in evaluating used test equipment options before purchasing. The last three companies I've worked for since 1998 made heavy used of equipment made before the date of your earliest 1983 catalog. Even now at work I use a...
You really need to size the transformer for the full 100%. Yes, the average current may be less, but the issue is the transformer core. To drive the 1-cycle sine the transformer core must not be pushed near saturation.
While I have no background in spacecraft, I do recall 44 years ago some basic from my "Statics and Dynamics" course. What is referred to as "dynamic acceleration" is probably just the next derivative of acceleration, or Jerk
Position
Velocity
Acceleration
Jerk
and a quick internet check shows...

According to the article, the 737-9 was new - just 2 months old. Brings up the questions. Had that door been properly latched/secured before the interior panel was placed over it? Or, is it some other kind of failure?
You never can tell where CS will take you. My son wanted both Comp Sci and a well known school, so he went to Ga Tech for his BS. Then GA for his Masters. He got exposed to a lot of research which led to doing research software tools for scientist at a research organization. Then to Cambridge UK...
Murph 9000 - you are thinking of United Airlines MD-10 Flight 232, aka Sioux City Iowa crash. The extra pilot was flying in a passenger seat and was called into the cockpit to help with the throttles.
This Alaska Airlines incident most resembles Federal Express Flight 705, April 7, 1994, that...
Transients.
Switch Mode Power has plenty of inductors as components and as parasitic inductance (wires and connections). V=L*di/dt Make dt small and V becomes big. And the whole point of power electronics is you are doing a lot of switching through inductors or motors. Plenty of voltage...
Seem to recall the V1 Buzz Bomb was made of thin steel and spot welded. Kept cost low and aluminum was a strategic material in short supply. A V1 cost less than 5% of what a V2 cost.
Not necessarily a good aircraft example as it only had to fly once for a few hundred miles.
You have to consider the entire system and not a single item. And then there is the reality. This article is only a week old.
Largest EV Charging Station In World Powered By Diesel-Powered Generators
When the Arrow program was cancelled, many of those engineers went south to the US. The space race had started and NASA was being organized. These engineers contributed to the Mercury, Gemini, and Saturn programs.
So, what are they using to connect steel hinges to aluminum body? Steel bolts?
Oldsmobile in the 80's changed from using a cast iron intake manifold on their V8s to an identically shaped aluminum one. But they kept the same die-cast thermostat housing and steel bolts. The bolts were indirectly...
