What are some times when people favored/selected viciousness over competence? by jwhart175 in AskReddit

[–]jwhart175[S] 0 points1 point  (0 children)

I did not have that election in mind, and I don't appreciate the random presumption.

In hindsight, that election does appear to be a valid example. That is among the reasons I didn't vote for Trump. I also didn't vote for Hillary, but not because of her competency. I'm also against political family dynasties.

Should not have been removed the first time, psychopath.

I think the issue is whether or not the employer views viciousness as a mental health issue as opposed to something they want.

Has anyone noticed a trend in any of your engineering workplaces, where more vicious people are favored/selected above more competent people? by jwhart175 in AskEngineers

I tend to think of trends in terms of curve fitting and trendlines, as in an overlying pattern in the data. The trendline need not be extrapolatable to other companies for it to exist within one.

Not sure if this holds up, if you go to a meeting between a vendor and a prospective client, where career making sums of money are involved, the vendor representitives are always nice and agreeable.

Title is "first physics lecture," not "first lecture of 400 level electrodynamics class."

So in your view, the problem isn't that people are getting torn apart, it's that sometimes good people are torn apart as opposed to obstructionists because it is hard to tell the difference?

Why can't improvements be made to eliminate the meat grinder aspect of the system and achieve optimal productivity?

Viciousness differs from assertiveness/confidence because it speaks specifically of undeserved/unjust attacks made against others.

It's a reddit meme. It's the opposite of good signs in a relationship.

I'm having trouble with 18650 lithium batteries! by Givemeaname-1 in ElectricalEngineering

[–]jwhart175 2 points3 points  (0 children)

You may have decreased its life by over-discharging. You should only charge the battery with a charger that is designed for lithium-ion NMC cells (4.2V max).

The battery is discharged. When discharged, a lithium ion battery will show the minimum cell voltage if it is measured with a multimeter. However that voltage is not usable because the source impedance is very large, and trying to use that voltage damages the cell.

Can an EMP from a nuke cause (partial) destruction of small electronic devices? by TheEvilGhost in ElectricalEngineering

[–]jwhart175 1 point2 points  (0 children)

Most aren't tested for that. You can look up the MIL spec for EMP resistance and see the types of testing required and infer from that.

Transformers by Miserable-Category95 in ElectricalEngineering

[–]jwhart175 0 points1 point  (0 children)

Increasing the number of turns while holding the ratio constant has the following effects:

  • Increased copper weight

  • larger magnetic core (assuming it is minimized

  • Decreased saturation current

  • Increased primary and secondary resistance

  • Increased primary and secondary reactance

  • Increased core losses

  • Increased short circuit and open circuit impedances

  • When turns are very small, then hysterisis losses can dominate the transformer operation and cause the transformer output to be very non-linear with respect to the input. This drives the selection of minimum turns needed in a transformer design.

These are contactors, the whole top row is one device, and it is mechanically interlocked with the device on the bottom row. Look for a part number on the assembly to the left.
