I believe a constant current power supply will provide better control but either type of supply will work.

LOL, when you mentioned a failed ferry and Tasmania I thought you were referring to the HST-2. They were built by Austal. Everything about the project has been a failure. In fact, Austal seems to be a plague on the world of Western ship building. Every ship they build is a failure. Despite that...

More than support, it needs mass. Using beams between roof supports includes some of the mass of the building to help reduce the magnitude of vibration. Look for regional code with regards to mounting air conditioning units to roofs for ideas.

You'll definitely want a central panel with your speed and AVR controls, volt meters, ammeters, synchroscope, and circuit breaker controls. This is the minimum for load control. Droop and mode can be set locally. However, there are automatic load sharing systems that combine all of this in a...

Induction motors in that power range are relatively tolerant of overspeed. I think you'd have a hard time finding one with a 3600 rpm rating that wouldn't tolerate 4500 rpm. Synchronous machines, on the other hand, have wound rotor construction and are sensitive to throwing the copper windings...

Dik, there are certain demographics that have much higher infant mortality rates. Infant mortality rates are much higher in countries with those demographics. Your refusal to acknowledge this only hurts those demographics. Your moral standing is low. You are placing politics above human life.

Was the cause of the 2019 failure ever released? There was a gas release which could indicate an explosion or an impact involving certain parts of the satellite. It appears now that two have "exploded". Do odds favor a debris impact in a portion of the satellite that could cause an explosion or...

I believe the information dik has posted to be true. The trouble is that he is making likely false attributions. His claims are easily explain through other observations. And with that said, 51 former intelligence officials... There is no credibility. Intelligence has perfected disinformation...

Pickling or electro polishing are options IF necessary. Stainless alloys have some desirable properties involving ease of storage and wear resistance that don't necessitate a perfect surface finish. Exhaust valves in engines are a good example. They rarely have the heat scale removed.

Norway and Iceland are very white. Infant mortality rates are driven by demographics, not spending.

The infant mortality rate of Cuba is the same as it is for the USA amongst white and Hispanic populations in the USA. Cuba is mostly white and Hispanic.

And what failure of the system lead you to require a 2 month stay?

I see supersonic flight as a mature technology. The SR71, XB70, and Concord all exceeded Boom's goals decades ago. I don't see the airplane scaling into a full-sized airliner. If successful, they're going to make a Gulfstream sized jet for the ultra rich that was developed using investment from...

Spin Launch is another example of a fraudulent company. This article reinforces that. They must be serious because they have a NASA like control room. Imagine the fireball if it left anywhere close to orbital velocity...

We can afford to lose Canada so hopefully the world learns from their example before it takes down the rest of us.

The carbon tube is going to have an irregular surface which is not ideal for clamping anything to. I would suggest fabricating a split collar or sleeve that you can assemble over your shaft with clearance between and use a pumpable or pourable epoxy to fill the space. Even better, remove the...

The greatest advancement in electric motors In 200 years is a motor that resists being a motor. That's an interesting statement to make. The BS bell rings with the proprietary dielectric fluid. Being dielectric does not make a fluid special.

Positions of power seems like the most likely place for DEI hires to land because their lack of qualification will have less of a direct impact.

There is zero deformation of any visible sections of the structure which leads me to believe the structure failed at the very end far from what we can see.

I notice that on both ends of the span, the last web does not tie in directly with the cord. Is this normal?
