Herman Trivilino replied to the thread B Simple mass/scale puzzle.The ceiling exerts a passive force on the vertical scale, unlike the active force exerted by the other bananas on the horizontal scale...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Free fall acceleration varies by 0.5% across Earth's surface at sea level. Probably not enough to bother with for fish, but it is for...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.See Post #113 for a revised version that hopefully addresses your concerns.
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Comparison by means of a balance is still the most precise way to measure mass.
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.If you tried to use that device in a place where the free fall acceleration were significantly different, you would find that it does...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Alright, here's a better answer. Referring to the figure in your OP, there are two hanging blocks, each of mass 10 kg. The block on the...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Well, it is a direct derivation of the scale reading for the given scenario. An elegant one. True, but it doesn't make your point...
-
I completely agree. If you have a force measuring device with two strings attached to it on either end, it's only useful if the...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.That in every situation where a scale is used, that's the way scales work. And proceed to show, by use of other examples, that that is...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.It would require that the spring constant be defined as ##k=2F/x##. A convention that I have never seen in the hundreds of textbooks...

Herman Trivilino replied to the thread B Simple mass/scale puzzle.Post #46.
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Why? Almost every bit of knowledge we gain involves a process of comparison to something else that we already understand. Anyway, the...
