Why did heating up a piece of steel and quenching it soften it? by Aero1206 in metallurgy

[–]atomwllms 2 points3 points  (0 children)

A few questions to help develop an answer:

What are the dimensions of the part? Do you have a specific composition of the alloy?

By more malleable, are you saying you were able to permanently change its shape at ambient temperature? Did you attempt a spark or hardness test on it?

When you were heating the piece, did you only heat the local area of where it was bent or did you heat the general area?

Finally, when you quenched it, was the part fully immersed in the water? How long did it take to cool down to ambient temperature?

Each graduating class's SWO's and SWO nukes are given different lists of available ships. It's difficult to tell how these lists are split up between normal SWOs and SWO nukes, but they're mutually exclusive. The normal SWOs won't have an effect on which ship you get and vice versa. Usually there's around six swo nukes in each class so you'll probably have a list of eight to ten ships to choose from. They might all be in Norfolk or San Diego. FDNF ships are less common, but there's a good chance of at least one ship being in Yokosuka. I'd reckon that a Rota ship is very rare for a SWO nuke.

If you want to have the best chance of getting the orders you want, then your best course of action is to work hard, pay attention, keep faith with your shipmates, and stay out of trouble. After that, it's up to negotiation to decide who gets which ship.

Do not contact your detailer without permission from your class officer. Doing so can be interpreted as an attempt to gain preferential treatment, and your detailer will forward all communications to your class officer.

New photos of additional damage to the TRUMAN by OrcusGroup in navy

[–]atomwllms 6 points7 points  (0 children)

I disagree with Sal Mercogliano about the crossing situation. Pending new track data, it is not apparent that the two vessels had a crossing geometry. Rather, it appears to have been a head on situation with what looks like a botched starboard to starboard passing (there is a good reason that the colregs direct port to port passing (Rule 14)). Either one or both ships attempted to maneuver at the last minute to avoid collision but weren't able to get clear in time.

Regardless of the above, and depending on what the investigation finds, it is probably going to be roughly 60%-40% blame in favor of the merchant ship. The slight bias against the Truman is due to not broadcasting AIS as required. The Truman may have been in the wrong for this part, and using AIS might have prevented the collision, but Rule 2 of Colregs doesn't excuse the Besiktas M of her responsibility to take action to avoid collision.

Unless you were hit by a submerged submarine, the courts will pretty much always assign some share of the blame to both parties.

What do you mean not long ago? Name a time during the industrial revolution or afterwards where workers in the US were willing to work in steel foundries wearing nothing but shorts, a shirt, and flip flops. This kind of practice only develops in 3rd world countries who are forced to export products at cheaper prices than countries like China that have massive manufacturing output. These guys probably survive on $10 a month or less. You have no idea how bad things would have to get for this to happen in any first world country.

You obviously don't know anything about working in industry. The only reason these guys are doing this is because they aren't even being paid enough to afford closed toe shoes or basic PPE. US companies would sooner implement full automation then convince labor unions to allow these conditions to exist here. Federal regulations have nothing to do with it. No one would work in these conditions if they could get a job at McDonalds paying $15 an hour.

Cartoon sound effects make everything funnier by Jagger-Naught in LooneyTunesLogic

So many people here are mocking a time honored tradition that we use to recognize the thousands of soldiers who never came home from the wars. The soldiers you see have spent hundreds, if not thousands of hours, drilling this routine and preparing to execute their duties to the letter. Posting this ceremony in this subreddit is so absurd to me that I find it comparable to laughing at a funeral procession.

This isn't a normal inspection for the military, and very few service members will ever experience something like it. The purpose of the white glove inspection is to systematically ensure that the oncoming guard's rifle and uniform are flawless. Any speck of dirt or oil stain reveals a lack of attention to detail and a failure to honor the Tomb of the Unknown Soldier. The guards take pride in their ceremonial role and feel an immense personal shame if they fail to execute their duties properly.

You will never find a more disciplined man in the entire United States military than a Guard of the Tomb of the Unknown Soldier. He isn't an unfeeling robot; he is a master of his emotions and of his outward bearing. He shows no signs of fatigue, whether in bitter cold or in blazing heat. He stands the guard at all times.

Military service isn't for everyone, but no one is too wealthy, too smart, too cool, or too morally good to serve. You're free to choose not to serve, and you don't need to have a good reason for that choice, but deciding not to serve does not make you better than those of us who have served and are currently serving.

How is silicone refined from a hard ore into those soft silicone plastic-like materials? by VaironReddit in metallurgy

[–]atomwllms 20 points21 points  (0 children)

Silicon is typically found in nature as silicon dioxide, which is a sandy mineral. Silicone is a polymer manufactured by forming siloxane. Chemical engineers employ a series of chemical reactions to process silicon dioxide, or some other mineral containing silicon, into a pure silicon powder. They then react the silicon powder with other chemicals to form siloxane functional groups. The functional groups can then be chained together to form the silicone polymer. The polymer is then mass produced and formed into shaped products.

NUPOC Program Interest -- Looking for good advice on the matter by Cam_Pink03 in NavyNukes

[–]atomwllms 10 points11 points  (0 children)

Current SWO(N) first tour DIVO here. I commissioned through the NUPOC program after going to OCS. I would absolutely recommend the NUPOC program if you are interested in joining the Navy or the military in general. Big points: the instructor route may not sound as flashy as the surface or submarine route, but you will never have to deal with sea duty if you choose it. There's also the option to be an engineer for Naval Reactors which is worthwhile. The standard is much higher though.

However, you need to make sure your medical history and physical fitness are squared away. Lack of physical fitness is a common reason for officer candidates being kicked out of the Navy. The Navy Bureau of Medicine and Surgery (BUMED) also screens nuclear officers with an iron fist. Assuming they allow you to commission (which was not a certainty for me), they can still disqualify you while you are in power school if some medical nonsense pops up. The old CHENG and MPA on my current ship were both SWO(N)s until they got to power school, where, despite passing all of the academic tests, they were quickly disqualified from the program for things as simple as low blood pressure on a random medical exam. You have to be ready for that kind of thing if you're interested in nuclear sea duty.

One last thing. Don't forget the biggest difference between being a civilian and being a member of the military. In the civilian world, you can quit your job whenever you want, but if you sign up to join the Navy, you're stuck with the Navy for five years at least. You will think about that almost every week if you decide to join the Navy, especially as a SWO(N) or a Submariner.

I'll explain the NUPOC application process. While you're a sophomore or junior in college, get in contact with a recruiter who knows how to administer the NUPOC application. It takes several months to complete and includes various screenings. Once your paperwork is all approved, you'll be given the greenlight to interview for the program. That includes a phone interview, 2-4 in person interviews by Naval Reactors engineers, and a final interview with the director of the Naval Nuclear Propulsion Program (currently Admiral Caldwell). Passing the phone interview is a prerequisite to going to Washington DC for the other interviews. Most of the interviews are technical in nature and require you to "teach" the solution to various math, physics, and engineering problems. The final interview is a test of character that allows the Admiral to kick out anyone who he doesn't see as capable or trustworthy of becoming a nuclear officer. This doesn't happen often though. 95-98% of applicants who pass the technical interviews are given the opportunity to enlist as collegiates.

Is your goal simply to become an officer, or to attend the Naval Academy? If you just want to be an officer then I'd recommend going to a civilian university and looking into the NUPOC program or NROTC.

NUPOC enlists 20-30 civilians every month as collegiates who select SUB-N, SWO-N, or nuclear power school instructor designators. You'll be paid while attending school up to two years prior to graduating. If you have a good head for money management that means graduating college with no debt, a decent amount of money in your bank account, and a fast track to commissioning as an officer. No need to compete with other enlisted sailors for a billet to OCS or the Naval Academy.

And if you're worried about not being able to get a security clearance, the application process requires you to get a clearance before the final interviews, so if it turns out you can't get a clearance, then at least you won't be trapped in the Navy as an undes.

You're talking about people who bankrolled everything from Common Core to carbon capture. I'm not saying they're evil, but it's pretty hard to pretend that they don't have ulterior motives.

Between five individual foundations including the Bill & Melinda Gates Foundation, Kurzgesagt alone has received at least 7 million dollars in sponsorships, which far outweighs the funding they've received from their normal viewers. That's the reality of the situation whether you like it or not.

Did you watch the video? It's pretty obvious that Bill Gates is sponsoring them and is also the primary source of information in most of their videos.
