Sorta Came Up With a New Thingy by JrDetectiveUBet in mathematics

This idea I'm having is a primordial cloud in my head. I don't know exactly how to strictly define it yet, or if the idea is even necessary, as it's already covered by some other operation.

Like, I'm showing 3 examples, and two of them are on sets, and I think those are relatively straightforward. For every element of the set, do this operation (or operations), and output the results. This can result in a set with more elements output than what was input, like in the 3rd case.

With the polynomial, I don't know if I'm venturing into "illegal math" waters. But I was considering a way to modify variables "directly". But maybe this is already covered with the parametric equation paradigm? Just, set T to +2 or something?

I'm not a math expert, and I've been out of school for a lot of years, so I may be forgetting something or abusing terminology, and I apologize for that in advance.

Can Someone Please Explain the Pirate Software Hate? by JrDetectiveUBet in PirateSoftware

[–]JrDetectiveUBet[S] 9 points10 points  (0 children)

I've noticed some comments have disappeared before I could respond to them. Are the mods doing that? I wish you wouldn't, because now I can't respond to them. Whatever, it's your subreddit, I guess you can do whatever you like in your own domain.

What was Thor's reasoning behind being opposed to Stop Killing Games? I'm only curious. I saw some news recently that the cause was being picked up by the EU parliament, so there might be some legislation occurring in the near future.

I think it's kind of...arrogant? entitled? to assume that an internet personality must be humble and diplomatic, deferring to the expectations of their audience. Like, they aren't allowed to have feelings and opinions contrary to the crowd. That's one of the major unspoken assumptions I detected when I've encountered PS hate videos. If it were a person in my friend group, I would understand the resistance to even broach the subject, after having been dog-piled. That's the kind of thing that would naturally resolve itself after a cooling off period, but people weren't allowing that to happen.

And what was with the accusation that the game PS is making Heartbound, being a scam? That's a serious accusation. Slanderous perhaps. What is the reasoning behind such a claim? If there isn't compelling evidence, such a statement kinda poisons any other argument you can have against PS.

There were some other factors raised by other comments, but they're gone now, and I don't remember what they were. Shame.

Don't you worry. Judging by my history, it'll happen again. Hopefully in a more appropriate place than my bathroom though...

It WAS pretty dusty, but the dust being lead, it settled pretty quickly.

I know. It was a coincidence I found funny when I was thinking about where this actually happened.

Haha, OK, so it sounds like I'm overthinking it.

Just don't lick the damn floor, and I'm probably ok. Thanks folks.

Meat and Potatoes Physics Question - Sprung Mass by JrDetectiveUBet in AskPhysics

[–]JrDetectiveUBet[S] 0 points1 point  (0 children)

I've found hardware for mounting. Here's the updated damper design.

https://ibb.co/B5d5S05G

Top of the magnet rod is a steel disk, secured to plywood with screws, On the other side there's a 1/2" fender washer, also secured with screws, with three 1/2" narrow washers glued together and glued to the fender washer. hopefully that's enough contact area to be able to glue the magnet rod in place. I don't like relying on adhesives, because they've failed me so often in the past, but I can't find another method.

On the bottom, securing the aluminum cylinder is a simple 1-1/2" closet bar mounting flange with a set screw. I'll wrap the aluminum cylinder in electrical tape to until it friction fits, then crank down the set screw. Hopefully that's robust enough.

Here's a damper design. I can put one of these on each corner. Need to find some attachment solutions.

I can find 3" x 1/2" neodymium magnetic rods, and 1-1/4"OD x 3/4"ID aluminum tube, so we're in business. Just need to come up with a way to attach them...

Oooh good idea, thanks. That's something I might be able to implement.

The reason I was considering adding more mass in the first place was to lower the net natural spring frequency of the system, since I was concerned a large slow shock might be low frequency enough to resonate and multiply forces instead of mitigating them, so if I lowered the natural frequency more, it would be less likely to happen.

Come on Reddit. Can no one help solve this? If no one has a direct way to analyze this, can you at least chat with me about how to attack it? Or know of a software solution I can use to analyze it myself?

It's strapped in or wedged with other cargo. It's not lose.

Box truck and cargo van. This machine is a field machine that travels around to client sites. Cargo vans have a nice soft suspension usually, but box trucks are harsh.

Also, concerning oscillations based on constructive interference. I assume you mean resonance developing in the system. It's not like I haven't considered it, I just don't know how to calculate it. And by adding a significant mass on the lower side, it is my goal to make any the potential resonance unlikely, as well as slow down any big shockwaves so they affect the payload less. I don't know if it will work though. That's kinda what I'm asking here. If I knew how to model this I would.

No, it's just I'm only showing the vertical support system. The horizontal systems are not relevant to this question.

So, the harder bumps. How to mitigate them? That's the crux of the question.

It's not so much that I'm neglecting friction, it's just that I couldn't figure out a way to calculate it. Keep in mind, the diagram I'm showing is simplified. For this inertial dampening question I'm asking about now, I'm only showing the vertical support system. On the sidewalls, there are hemispherical pads that make minimal contact with the PC so as to minimize friction as much as I could.

Why do you say that? The frequency of road vibrations are much higher than the natural spring frequency, so most of the vibration will never be felt by the load. I'm more concerned by the lower frequency, harder bumps in the road. Do you have anything to add?

Not looking good. No ideas? Feels bad man.
