aas Bandit posted:Seems like this could potentially go very badly if there were two small divots/imperfections on that sphere that happened to line up just so...super low odds, but it would be interesting to see. It's a sphere of (seemingly) greater hardness than the spools. It's not even in the mesh plane, there's nothing to grab. That's why it wanders back and forth. It was probably designed to make sure light materials all get thrown into the mesh plane and shredded.

Is prompt supercritical similar in its intent to the phrase 'rapid unplanned disassembly' or 'rapod-ox event'?

Ok so it's a failure mode that reactors are designed to absorb and super-criticality doesn't necessarily mean you explode, just that you maybe hosed up your fuel/reactor chamber.

Phanatic posted:That's the thing: "critical" means a steady-state, which implies that it's controlled. In films it's used to mean "oh poo poo," but in the real-world it means the opposite of "oh poo poo." Sick! Thanks! I like how elegant nuke control is. I guess I was strictly talking about prompt supercritical but didn't appreciate the difference in the technical terms.

Factor of safety for shipping rigs and ground support equipment is like 5x gravity load. Cranes could be built with strain gages and frangible bolts so that if the crane detects overload for its setting the system blows the bolt and brakes the hoist winch so you can't retract the cable, but you can still take it back to a licensed dealer for an easy repair with proprietary tools. Of course some jethro will find a way to defeat that.

They're also concerned about pilots skill levels after being furloughed for a year.

haveblue posted:Is this one of those things where the problem is that no one considered two things looked confusingly similar and the solution is to switch one of them to a design that won't physically fit in the other? Exactly. Or you make them exactly the same so you can leverage economy of scale if the parts all serve a similar purpose, in this case, pinning the NLG. The rub comes when a mechanic drops a part and doesn't know/ care that it happened. Nobody admits to that poo poo. EG for interchangeable parts: In the engines, the borescope port plugs are painted so they don't accidentally dump their oil on the tarmac or unbolt something on the line that they can't re-torque on the line (FAA Regs prohibit certain maintenance operations unless certified).

Platystemon posted:Yes, nearly everyone calls steel spheres “ball bearings”, even if they were never intended to bear anything. They are wrong and I will die on this hill. I'm pretty sure a bearing pack is made up of races and bearings. The races being the little rings, the bearings being the balls/pins/ cones/etc. Between races. Mods, please rename me Cones Between Races.

DandyLion posted:Also something I couldn't figure out but I always noticed the F-16's sounded way louder even though the F-18's had two of those engines.... The engines are designed to be quiet. Acoustical vibes can destroy an aircraft engine. The sound is made by the fan throwing air into the compressor (military fighter engines are low by-pass turbojets, not high by-pass turbofans), then shooting it out the rear end as fast as possible. Commercial engines try to move more mass, but slower. Mass flow rates can be comparable. The flow recombination makes the noise. You're hearing the engine push on the air around the plane so hard it's like shooting a water jet at concrete. Airframes are designed for 'low observables' so there was probably a change to make the sound less noticeable from the frontal hemisphere. The military doesn't give a poo poo if you hear the plane after it passes. It's already too late at that point.

Bridges usually have a pin joint at one end of a section and a flat plate or dish on the other side to mount the road surface platen on. Sometimes the mounts are even dampened. Gotta make sure the road isn't over-constrained. Concrete doesn't like bending moments.

Bloody Hedgehog posted:If money is no object, sure. But it is, and no factory has the tooling or molds to produce the thousands of parts needed to build a steam engine. Steam power is deceptively simple and we're much better at making wild poo poo than the we were in the 1860s. 3d printing obviates the need for casting for small runs and high end manufacturing is going closed-loop finally so CNC accuracy is wild. We absolutely can make them, and I see another train weird showed that too. It's mostly a question of how you produce the steam engine most economically for your market. A steam train may be more attractive for a sugar plantation since they'll have ample plant matter to feed boilers with as part of processing.

Spatule posted:It gets better: mechanical stress (say, some ways of forming a bolt's head, or shredding for recycling), can alter the magnetic properties of SS. Suddenly you get parts half magnetic, half not, or your ferrous fraction gets polluted by what used to be non magnetic stainless steel (if you use a stong magnet, the effect is weak). Just hit it with a hammer or something. I used to demag parts during machining by hitting them with a machinists peen.

Mr. Nice! posted:with super hard and uncuttable rings, you can shatter them pretty easily. Take a standard vice grip, close the grip over the ring, and tighten til the ring is comfortably gripped. Release the vice grips then tighten another 1/4 turn or so. When you close the grips again over the ring it will shatter. Not inconel, it's fairly ductile for its hardness. I think you're thinking of metal composites like tungsten carbide.
