I already understood all that coming into this. So why not say "a scale measures mass by using the force applied on it", instead of it saying it "measures mass by measuring force" (very confusing statement).

Like I said. Oxford and I and many others understand the word 'measure' to be the end result of a measurement procedure. Oxford "ascertain the size, amount, or degree of (something) by using an instrument or device marked in standard units or by comparing it with an object of known size."...

Here is another perfect example of what I am contending here. In this thread the guy is trying to understand what a scale is measuring and as usual Doc Al comes in and throws the following wrench in and confuses EVERYONE including me and has me second guessing my understanding. Doc Al: ...

I COMPLETELY understand that. I also understand that if you want the most accurate measurement of your mass then you need to stand on it in the factory where it was calibrated since gravity's force is not constant. My replies in this thread has changed the subject to me taking a stand against...

If it was labelling force in mass units it would show "667 kg" (would correctly be labelled Newtons) instead of 68 kg.

I said 150 lbm is my mass and if I were on the moon it would STILL BE my mass (150 lbm). Is that confusing? Actually sir, I contend your statement is confusing and if I didnt know anything about physics and you said ... ... I would take that to mean - by reading it literally as you wrote it...

This is absolutely incorrect sir and all this does is confuse the heck out of someone when you say it. It may use the force pushing down on it by procedure but it is not what is ultimately measured. The mass is measured and correctly labeled in kg or lb (lbm). Oxford defines measure as...

Since 97% of everyday weight scales (both in doctor offices and at home) measure our actual mass either in lbm and/or kg, and NOT force (lbf or N), then why does oxford choose to define weight to be relative? "a body's relative mass or the quantity of matter contained by it, giving rise to a...

this confirms my suspicions. thank you. most people never realize this until the see both the abstract and physical versions of electrical construction, and it is never actually mentioned point blank in physics texts, but AC primary sources are actually connected directly to ground and is...

transmission circuits don't have a return (neutral) wire. so it must go to ground. also... neutral wires on distribution circuits are connected to ground at poles so it never makes it back to the substation. in either case, the circuit never makes it back to the source. nevertheless, is...

K. I guess I must be misunderstanding something. This is how I've always visualized how high voltage (power line) transformers (7 kV, 36 kV, 500 kV, etc...) are hooked up. Am I wrong?

k... now I am confused... taking what Nugatory said into account... A/C transformers primary coil are a direct path from hot ( >4000V ) to ground/neutral (unless you are considering the reactance of the inductor coil)... so why don't A/C transformers in substations and on poles blow up when...
