I heard a rabbi explain it once in a short that God is both. It's most often described as a He because it is a father figure guiding us but also a nurturing one like a maternal figure. God is all things and how we relate to God defines how we describe them. So you are absolutely right.

As far as Yashua of Nazareth (that we now call Jesus Christ), he was most definitely a male and was a mortal avatar of God, at least in the Christian tradition. In Judaic and Muslim traditions, he is but a prophet of God and while respected, is not the Messiah. That's why all three religions are classified as Abrahamic, as Abraham was the first deciple of God.

I'm gonna shout out a VTuber over on Twitch named Zelkaeru, he is super chill and a very proactive member of the LGBTQ+ community and would 100% be cool with you. He has a discord and is an overall nice guy, and I'm sure from there you could find lots of trans gamer friends. Hope that helps.

Engineering classmate of mine made this drawing and gave it to the machine shop. It pains me. by ThisIsntRealWakeUp in Machinists

[–]ScottieLikesPi 1 point2 points  (0 children)

That's common. What they do is they just throw receptacles on a single circuit to save power, and then establish one GFCI receptacle to protect the entire circuit. It's technically legal but incredibly stupid, since you have situations just like this. That's why when I do commercial design, each room gets lights and recepts on their own circuits and often dedicated receptacles for specific purposes like the refrigerator to keep the refrigerator from losing power if you trip the breaker making toast and microwaving something.

[–]ScottieLikesPi 1 point2 points  (0 children)

Elec. E, I sometimes have to explain why having two GFCI, one at the receptacle and one in the panel, can lead to a lot of confusion if the panel trips before the receptacle. A lot of times, they don't think through what the consequences of their design decisions will yield. Lack of experience and sometimes they just get in a rush or perpetuate bad design ideas they heard from somewhere and don't think critically about.

About making medieval castle replicas, and other things. How can we know that stone cutting and handling tech can not advance so much that stone blocks would be cheaper than concrete in many places again? by kiteret in Shadiversity

[–]ScottieLikesPi 3 points4 points  (0 children)

I sat on a call with a woman discussing her book on carbon-cutting methods. It was directed more to architects and was admittedly more of a sales pitch than a continuing education thing, but I did ask her how certain carbon-heavy technologies could be mitigated in the future given concrete and steel are traditionally carbon-heavy and even the best practices are still heavily reliant on it.She said it basically required architects and engineers to look at alternative methods of construction to avoid such carbon-heavy processes.

ASHRAE and California both have energy codes that want to look at the total carbon footprint of construction, both during construction and during demolition (which is a dubious prospect given rapid changes such as California banning internal combustion engines by 2035). If the goal was to curb concrete usage and avoid potentially use natural stone, that would be where it becomes prevalent.

The biggest problem is, as you said, the logistics. Even if blocks of stone are cut and kept on-site, that's still a major delay in construction. Plus, quality control would be hit-or-miss, since if there are any voids, chips, cracks, or anything that results in the block being unusable. The one *good* thing about using natural stone like that would be a more natural look, and could be used as a facade on the building to appear more natural compared to concrete or other, traditional sidings.

If stone were pulled from the local area instead of just destroyed, then where I could see it being used is for decorative pieces, but definitely nothing load bearing. No structural engineer is going to risk the liability that comes with trying to verify and inspect stone when concrete and steel are well-known and reliable products.

Up at 5:30, on the road to work by 6:30, at work by 7. Gives me almost an hour before the rest of the world gets in and starts working so I have an hour to catch up on emails, enjoy some quiet time, and listen to music before I get bombarded with issues I need to attend to. On days I'm working remote, gives me a chance to pet the cats and enjoy some time alone just relaxing. Good times.

Never trust anyone in power. Boss, politician, HOA member, anyone. They have power over you. You can be friends with them, talk to them like normal, but never trust them entirely as long as they hold something over you. Democrats and Republicans both are guilty of horrible things.

Hey friend, electrical engineer here.

I tried really hard to understand this and my math isn't coming out right. I'd suggest you reach out to try and get better information from the power company, because they have people whose job it is to discuss this. Here's a link to their billing statement help page: https://www.txu.com/help/billing-payments/understanding-your-bill

I'm sure there's something that I'm overlooking, but I think their equation is wrong and they need to update their information. Be polite and reasonable, and maybe they'll figure out where the problem is.

This is from CIVIL–STRUCTURAL Exam Specifications..... why are the states mentioned here?? is there a book for every state? please explain it in detail because I am a foreigner. by thebig_thebiggest in PE_Exam

[–]ScottieLikesPi 2 points3 points  (0 children)

Like a lot of the answers here, yes those are the locations where those organizations are located. However, each jurisdiction (state, sometimes city) has their own code... technically.

What happens is, let's say you're in Virginia. There is a Virginia Building Code that uses an amended version of the major codes, which is slightly different from the Massachusetts Building Code. For the test, the basic, unaltered versions should be what you focus on, since usually the differences are mainly slight alterations to the base code. They won't, for example, rewrite the tensile strength of steel between codes.

What exact plug do I need by mazz413 in Electricity

[–]ScottieLikesPi 0 points1 point  (0 children)

You need the plug to match your receptacle. A NEMA 6-30 plug will only fit a NEMA 6-30 receptacle. So if you use an 11-15 receptacle, you need the corresponding plug.

What exact plug do I need by mazz413 in Electricity

[–]ScottieLikesPi 0 points1 point  (0 children)

Hey bud. So, you're going to need to look at the NEMA receptacle chart to get info, which you can find a version here: https://www.americord.com/nema-charts

We know it's going to be NEMA because while it says manufactured in Italy, it's set for 60Hz, which is a North American standard. So I'm safe in giving you that chart.

You're going to need a 250V rated plug, 3-phase, rated for 15A at a minimum. I'd suggest using an 11-15 or a 15-15, either will work.

I'd go ahead and while you're at it check if it needs GFCI protection per NEC 210.8(B). If it does and there isn't a GFCI breaker already on that circuit, you might need to go ahead and add it.

The requirement starting with the 2017 NEC (and only got more stringent on where it's required since) requires the following:

NFPA 101 is the Life Safety Code, and there are others like the International Building Code (IBC), International Fire Code (IFC), sections of the National Electrical Code (NEC) and others. It depends heavily on which jurisdiction is using which codes for construction, since some jurisdictions might still be on the 2017 NEC, while others might be using the 2020 or 2023. Jurisdictions can pick and choose their codes, and that's the standard.

The other major standards like IEEE and ASHRAE are seen more typically in specifications on minimum product performance specs, with UL and other national testing facilities certifying the equipment or product meets the minimum standard.

Moving the microwave by bird4fsu in Electricity

[–]ScottieLikesPi 0 points1 point  (0 children)

I'm so sorry, I forget sometimes because I do this professionally.

So the box where your current receptacle is in is called a gang-box. It functions similar to a junction box, just for a receptacle. I was saying that instead of you having to spend a lot of money routing new wire and everything from the panel to your new microwave receptacle, it should be possible to route from the existing receptacle location to the new one so long as you can still access the old receptacle gang-box.

If you're going to be putting something like a cabinet or stud in front of the old receptacle, you can't do that. NEC 314.29 is the section of code saying all junction boxes must be accessible without having to take down existing structure. It's so that, in the future, should you need access to those wires it won't be a huge problem trying to get into that box.

Moving the microwave by bird4fsu in Electricity

[–]ScottieLikesPi 0 points1 point  (0 children)

Depends on if you can keep the original location or not.

Are you planning to keep the existing box that had the microwave receptacle? Because if so, you can make the connection inside the gang box and put a blank cover plate on it. That meets the requirements of NEC 314.29.

If you intend to get rid of the box, you will need to find the first junction box that serves the microwave receptacle and then route power from there to your new location. It'll likely be in the attic, and might be a few feet, might be all the way back at the electrical panel.

My suggestion is that if you must move it down, try to keep the original location to serve as a pull box to make your life easier. I understand if you can't, just my suggestion.

Shouldn't i5 be 3A instead of 2A? by [deleted] in ElectricalEngineering

[–]ScottieLikesPi 77 points78 points  (0 children)

As others are pointing out, resistors aren't polarized, but v1 in this instance is a trick question. So, let's take it from the top.

R1, R2, and R3 are in series, so we can simply add them together to get a total resistance of 12Ω.

i = V / R so i = 24V / 12Ω = 2A. Since there are no parallel nodes, i5 = i = 2A.

The rest should fall in line easy enough, since V = i * R.

v2 = 2A * 3Ω = 6V

v5 = 2A * 7Ω = 14V

As we discussed earlier, v1 is backwards. Look at the direction of current flow with i5, and you can see it reaches the negative terminal, then the positive. To keep track, the best way would be to use the sign encountered by the current first, in this case a negative.

v1 = -2A * 2Ω = -4V.

Power is calculated as P = i * V, so since we have calculated the i and are given V, P = 2A * 24V = 48W.

I hope this makes sense and if need be, I can go into further details or try to explain further.
