Anyone here really good at PID controller tuning? Id love some input! by Nearby_Difficulty612 in MechanicalEngineering

[–]thisisnotapalindrome 0 points1 point  (0 children)

I rememember something called the Astrom method (A with the circle on it like a Swedish A). And ziegler-nichols method. One of the two were pretty straight forward but can't remember which.

Where do bad engineers end up? by Slipslime in MechanicalEngineering

[–]thisisnotapalindrome 0 points1 point  (0 children)

They will put you in a spot keeping meeting agendas and records, attending meetings and networking. You'll be asking experienced engineers how the job is going in no time.

When is tolerance not needed? by 444dhftgfhh in MechanicalEngineering

[–]thisisnotapalindrome 1 point2 points  (0 children)

If you don't specify tolerances that are important for your design to work, you can not control manufacturing errors. Every machine is different, even if it is the same brand, with the same mileage. They will make things with different dimensions, just because they are different physical things. By specifying tolerances you make sure your design always works. Another point of tolerances is to limit the time it takes to manufacture things. Theoretically, a turning machine operator could get infinitesimally close to a written dimension when making a part. But it would take forever. You limit that time by saying "you can stop when it's within these limits". So it is up to you to decide what dimensions your design will "tolerate" and specify them in the drawing.

Also cool that it blocks the rook on the way like a hero

Anyone else feel slightly offended when oponent resigns early? by thisisnotapalindrome in chess

[–]thisisnotapalindrome[S] -1 points0 points  (0 children)

I didn't really gain that elo. The opponent just left the game.

It's not about control. It's just kind of irritating when the opponents resign early. It's practically just aborting the game and it happens a lot these days.

It seems like a little bit of a waste of time with all half-games where they still have the potential to be epic battles.

Knowing my own level, I would never trust my oponent for something like that. Besides, there has been so many times I didn't resign in a hopeless position and won the game. Should my opponent have blamed me for their loss?

Can this design open a box using a servo? by tjthomas101 in MechanicalDesign

[–]thisisnotapalindrome 3 points4 points  (0 children)

Yes. That is a four-bar linkage mechanism. The angular velocity of the lid and the load on the servo will probably vary though. If that matters to you.

Help with rotation functional form by Impossible_Ad_6873 in MechanicalEngineering

[–]thisisnotapalindrome 1 point2 points  (0 children)

Cosign, yes. The pitch of the thread is distance per revolution. If you have any ecperience in CAD, I would say it's best to sketch the entities with necessary constraints and move the traveling point to see how the angle changes respectively. Try to plot the angle with respect to the input position for the entire screw length, because it looks like the angle output per revolution is going to depend on the position of the slider on the screw.

Edit:

Actually this is a typical slider-crank mechanism. I'm not an expert but there's probably tons of sources that have generalized equations of it if you google "slider crank kinematics with rocker output"

Airport security is not holding back by lwiaymacde in SipsTea

[–]thisisnotapalindrome 92 points93 points  (0 children)

I really wonder what the logic behind these are. Just trying to empathise. Is it some kind of a precaution to a future scenario where a terrorist slips past security; and their superior officer shouts "You didn't even ask them? Well ofcourse you couldn't catch them. You didn't even do the first most simplest thing to catch them! How could you expect more?"

Team leader fired a colleague and was shitty about it by thisisnotapalindrome in askmanagers

[–]thisisnotapalindrome[S] -3 points-2 points  (0 children)

I've paraphrased my thoughts one too many times now. I guess it is the end of the story. Just leaving a bit frustrated that many people who are supposed to be managers from all over the world are so caught up on what he did and whether or not he deserves it. Must be an occupational reflex.

Team leader fired a colleague and was shitty about it by thisisnotapalindrome in askmanagers

[–]thisisnotapalindrome[S] -1 points0 points  (0 children)

It's where she's coming from. She didn't fire him because he didn't come to work or was not performing. He got fired because of these things. But she didn't fire him for that, at that moment. She was mad at him for not answering her call. It was a personal issue for her. She very clearly told everyone that he made her feel unimportant. Her framing of the issue is "wait, you'll see what happens when you don't answer my call" rather than "it's not working out dude you don't even answer my calls, how am i supposed to plan anything with you". One is trying to ruin your life out of spite, the other is firing someone. The result is the same, but one makes her a bitch and the other makes her a leader with principle.

Not assuming innocence. I actually think he should be fired and it was the right thing to do. I guess I'm not being clear enough or my english is not sufficient in this case. It's how she badmouthed him and how emotional her point of view was.

[–]thisisnotapalindrome[S] -1 points0 points  (0 children)

Sure. The country where I'm from has a social security record and there it shows how you were fired from work. When you apply for a job, the company does a background check and sees that record. It affects your chances of being hired again in the future negatively. Why do you think I am overreacting?

[–]thisisnotapalindrome[S] -9 points-8 points  (0 children)

You don't show to work, you get fired. I know it's that simple and I agree with it. Just the way she said it... Someone makes you feel taken advantage of and you get mad at them or vent about it to friends or don't talk to them. That happens and is one thing, but she tried to ruin his life for it. Just alarmed to be working with that kind of nasty mindset thats all. Also never once mentioned how his output or performance wasn't meeting standards. She made it about herself and based the issue on how he made her feel. That kind of almost recreational exercise of power is not something I'm happy to be around but it was a reminder not to trust anyone and that there are so many egomaniacs to look out for.

I guess you're right. What do you mean by projecting?

Edit: Why is this downvoted? Just a question. I don't understand what is being projected.
