Herman Trivilino's latest activity
-
You talk about masses not forces. Thus you ignore the force that is always needed at the other side of the scale, even in the simple... -
Herman Trivilino replied to the thread B Simple mass/scale puzzle.But that is the process of altering an intuition. It won't change by itself, and leaving it unchanged means a discord in your own...

Ok. I'm out. I thought about it in terms of a tug of war, couldn't figure out the answer, found the following video, and the...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.The ##\mathrm{SI}## unit of force is the newton. Weight is defined in physics and engineering differently than in international treaty...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.There are ways to measure force that don't make use of springs. They all share this property, though, that if you apply forces of equal...

Herman Trivilino reacted to ergospherical's post in the thread B Simple mass/scale puzzle with
Like.
That's just a misunderstanding of how springs work. If the tension in a spring is T, the spring exerts a force of size T on anything... -
Suppose I asked you to answer the following binary choice question. The figure on the right shows a 10 kg hanging mass connected to a...

Herman Trivilino replied to the thread B Simple mass/scale puzzle.It wouldn't be a valid measure of the force needed to open the can. Instead of putting weights on the can you could have just held the can.
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Well, gravity doesn't fit this scheme. But otherwise, an active force is a force that arises from the expenditure of fuel. A person...
-
I remember being confused by it the first time I came across it. The experiment we did at school was to measure how much force was...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.It's essential that they understand that it's always due to a deformation of an elastic material, whether it be a stretched cord or a...
-
Herman Trivilino replied to the thread B Simple mass/scale puzzle.Perhaps I've interacted with a lower caliber of student. But in my experience they don't demand or even ask for a formal solution, and...
-
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...
