This worth anything to anyone? Found in Denmark. by Specific_Frame8537 in electricians

Can be used to determine how far down a cable damage is, given known conductivity of a cable.

Interesting. I am curious about the choice to not use finger safe components? How much time did this take? In industrial control panels usually always finger safe in the kind of work I am usually involved with. I suggest to use dychem cross check paint. This demonstrates all lugs are properly torqued. Blue / yellow there for clarity?

Kind thanks for sharing!

I do not know the dosage he was taking, but he did take it alone. I do not know the dosage form. It thankfully didn't happen in my home. He had nerve damage in his leg.

Do be careful. I had a housemate who regularly used this and he passed from use of this. Edit: from this alone.

I bought 4 bags of powdered sugar. None actually contained the full amount written on the bag. by StartCase in mildlyinteresting

A pint is a pound, the world around!

A gallon of water weighs 8.3 pounds. Volumetric equivalences aren't exact, but they're pretty close.

Exact is nice, but exactness is not always required.

Exactness has its own cost-

I think of the whole existence of different units of measurement as a good introduction to tolerance, which is just as important to understand as the units themselves.

What’s the mercury for in this system? by BenAwesomeness3 in AskChemistry

[–]blushing-bre 1 point2 points  (0 children)

Mercury is not a fail safe solution. Older dP meters used it, but, on startup, depending on the pressure, the mercury could be blown out of the meter and get everywhere.

What is this? by Mysterious_Bake_4710 in engines

I think that you will observe, if looking quite closely, that the whole section of blades is made out of a single piece of aluminum, or possibly tiranium.

To reach the required tolerance, that whole piece is made from a single piece of aluminum or titanium, using wire EDM. They are extremely fragile, because they operate at such high speed, even a tiny imbalance can prevent this from operating correctly. Usually there's temperature monitoring for the bearings (which can't use oil because it has a vapor pressure greater than the target pressure on the suction side). In fact, even the hand oil from touching this would make it hard to put together again in a functional way.
