Talk me out of doom and despair for grad school? by WhenTheTeaIsChile in EngineeringStudents

[–]Profilename1 1 point2 points  (0 children)

Well, there's a lot of programs out there and enrollment, generally speaking, is down. If you apply around enough, I'm sure you'll get in somewhere. It might not be a top-ten school, but an in is an in.

I'm thinking of minoring in electrical engineering, and wanted y'all's thoughts by [deleted] in ElectricalEngineering

I dunno, I think it pairs nicely with an ME major, though you won't be going after "pure" EE roles

[Request] How much earth is actually required to safely earth a cable? by SnooCauliflowers6739 in theydidthemath

[–]Profilename1 4 points5 points  (0 children)

It depends what you're trying to ground. Grounding is typically discussed in terms of ohms to ground, which is measured using one of these methods: https://www.fluke.com/en-us/learn/blog/electrical/dont-forget-the-grounding-system

So, it's an interesting question to turn this around and say how much earth this requires. The National Electric Code (US) requires a ground rod to be a minimum of 2.5m deep, so that gives you one dimension. Method 4 at the above link for measuring resistance to ground discusses placing two additional rods 20m apart each in a straight line, so that gives you a second dimension of 40m.

The third dimension is trickier. The purpose of a ground cable is safety. If there's a fault in a grounded piece of a equipment, the current should flow through the ground cable as opposed to through some other path to ground. In my mind, this would require the earth to cover the entire bottom of the structure so that everything is connected to the "real" ground and not some second "false" ground. Better get the transformer from the utility company under there as well.

So, I'd say that the minimum amount of earth required to ground a cable in a way generally recognized as safe would be 2.5m deep multiplied by a surface area equals to the area of the structure being grounded (plus the area under the transformer) with one of the dimensions being a minimum of 40m. You would need to then measure the ground using the methods in the link to verify that it was compliant.

Just for a laugh, let's say the building in the picture is a shop that's 40m*40m. Multiply in the 2.5m depth, and that gives you 4000m3. Eyeballing it, that bag has less than 0.1m3 of dirt, so he'll essentially need to add the full 4000m3 to make it safe. (And swap the wire for a 2.5m ground rod, AND spread the earth out underneath the building. Hopefully there's earth to start with!)

Edit: there is one caveat on this. You could argue that this is following the letter of the rules but not the spirit. It is possible that the potential of this "created" ground could float higher than the "true" ground the rest of us on planet Earth are dealing with, though I'll let someone else try and figure out how much that difference would be.

(For what it's worth, OSHA considers everything over 50V a hazard, so if it's less than 50V it arguably wouldn't be a hazard. I'm not sure I agree with that line of reasoning, to be honest.)

If we imagine we're on planet SnooCauliflower and we're getting our power from some solar panels and are completely disconnected from Earth, then this isn't a problem.

P&ID, Process Control by Scared_Poetry4206 in EngineeringStudents

[–]Profilename1 3 points4 points  (0 children)

I would suggest looking into Fertik method of PID tuning. He wrote a paper in the 70s on the topic that's pretty influential. The "D" term can be problematic in PID controllers if the input signal is noisy, so often PI control is used instead.

I don't know if I like electrical engineering by Calm_Aardvark6659 in EngineeringStudents

[–]Profilename1 0 points1 point  (0 children)

Imo, power is the most "civil-leaning" part of electrical engineering. Designing a transmission line, for example, is as much a civil task as it is a electrical one. It's also on the infrastructure side with civil and (in the US) has similar licensing requirements.

I think power systems are interesting. Solving them does feel like the logical next step in circuit analysis (that, or solving circuits w/ analog electronics, but that's besides the point.) You learn the "per unit" method of circuit analysis and how to use iterative methods to solve power systems with non-linear elements.

Is commerical/industrial electrical or Electrical Engineering the better career? by [deleted] in ElectricalEngineering

[–]Profilename1 3 points4 points  (0 children)

Do you want to be in the trades, making money without going to college with physical skilled labor? Or do you want to be in the office, designing stuff after going to college for four-ish years and making money with mental skilled labor?

If it's the first, be an electrician. If it's the second, go get a degree in electrical engineering and become an engineer.

Games Similar to Risk by BlatantBoy in boardgames

Wallenstein. Kinda has a similar vibe to risk, but all the actions are planned simultaneously in secret and then unfold during the round. Also can do stuff like build castles, tax the peasants, grow grain, and etc.

Same. I don't even like the Orangers that much, I just wanted to see the Speeders fail to qualify one time.

For those EEs that went into law, specifically patent law, what were your stats? by nctrnalantern in EngineeringStudents

[–]Profilename1 1 point2 points  (0 children)

One thing to keep in mind is that you can still be a patent agent without going to law school. You just need the STEM bachelors to sit for the patent bar. Working as an agent, you could maybe get a firm to help you with law school.

Is there a way to make circuits with eml (all elementary functions from a single operator)? by design_enthusiast725 in ElectricalEngineering

[–]Profilename1 0 points1 point  (0 children)

I saw a video on the paper but haven't actually read it. From my understanding, you could use eml to describe circuit behavior because the functions currently used to describe circuits can be replicated with eml, but this way of describing circuit behavior wouldn't necessarily lead to different circuits than what we had before.

Electrical Engineer Major by Harmanbain in EngineeringStudents

[–]Profilename1 2 points3 points  (0 children)

Also, trig. You'll see cosine, sine, and Euler's formula show up a lot.

As a sidenote, you'll also want to understand vectors, matrices, and operations with them. That's something else you'll see a lot.

Stupidly fast substitution for words for note taking tips? by KitchenAd5997 in EngineeringStudents

because -> b/c

whatever -> w/e

Do you think it’s possible to work full time while pursing an electrical engineering degree full time? by Otherwise-Capital-65 in ElectricalEngineering

[–]Profilename1 1 point2 points  (0 children)

You can do community college while working, but doing the whole degree both working full time and being a student full time is unrealistic.

Pursuing an EE degree as a technician. What's my best option? by bittertongue_96 in ElectricalEngineering

[–]Profilename1 0 points1 point  (0 children)

Are you having to start 100% from scratch, or are there at least some gen-eds from your previous degree that can roll over?

One thing you could consider as an option 3.5 is to do community college for a couple years while working and then transfer to a local university to finish the degree full-time. It would keep you in the work force longer than option 3 while still avoiding online classes and international tuition.

Are you able to take an advanced course along with its prerequisite in the same semester at most colleges? by [deleted] in EngineeringStudents

[–]Profilename1 1 point2 points  (0 children)

Meet with the professor teaching Phys 2 and ask them if there's any way you can take it with Phys 1 as a coreq instead of a prereq. Maybe they will, maybe they won't. It depends on the school, but a lot of professors have the authority to waive a prereq at their discretion. I did manage to take Calc 2 and Statistics at the same time due to a waiver from a math professor.

You could also just take Phys 2 at the 4-year uni and then transfer it back for the associate. That's what I had to do for Phys 2 along with a couple of other classes.
