DaveC426913 replied to the thread B Simple mass/scale puzzle.Yes. Now, can you demonstrate that in one diagram, without resorting to altering the scenario (the string) and then explaining that one? -
DaveC426913 replied to the thread B Simple mass/scale puzzle.Oh. I see. And now I see why it has to be in Newtons, rather than in kg. The right diagram wouldn't make sense in kg.

DaveC426913 replied to the thread B Simple mass/scale puzzle.How does this relate to the diagram? I see only one instance of "10kg" in that formula, yet the digram contains two.

DaveC426913 replied to the thread B Simple mass/scale puzzle.No. It really would require 6lb of bananas for the a scale to read 6lb. I think we are talking past each other. Those 3 lb of bananas...

Informative.
Or some sort of wedgy thing you can cobble together from wood scraps. Expect it to slip at some point, just to be safe. -

DaveC426913 replied to the thread B Simple mass/scale puzzle.I don't want explanations. I have explanations. I even have my own. I know it is, in fact, 10 and not 20. The answer is not in doubt. I...

DaveC426913 replied to the thread B Simple mass/scale puzzle.Yes you have. It's not resonating. Because you're still not explicitly saying why it's 10 and not 20. Sure. But why not 20? (Do you see...
