AI Thread Summary
A Sankey diagram is a specialized flow diagram that visually represents the flow of resources or energy, with the width of the arrows indicating the magnitude of the flow. It is particularly useful for illustrating complex data relationships, such as energy efficiency in various sources like solar, wind, and geothermal power. The visual representation aids in understanding and communicating information effectively, making it beneficial for presentations and educational materials. Users often seek examples or tools to create these diagrams, especially for specific applications like electricity efficiency. Overall, Sankey diagrams serve as a powerful tool for visualizing and analyzing data flows.

What do you honestly define a sankey diagram to be? I really don't think there's any point in using it. I mean, why would it help someone, what is the meaning of it and how is it used or when is it used..

I really don't have an understanding of this..maybe you do?
 
Engineering news on Phys.org
They give good visual representations and are useful for displays such as posters.
 
Anyone else? Any more advantages for using it? Any way you could describe to a friend what it is?
 
? Not much help lol.

I need help finding one for Electricity efficiency. Solar, Wind Power, Wave Power, GeoThermal etc.
 

Thread '2:1 Pulley Question'

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...

Thread 'Why do all my clocks run slow?'

Hi. I noticed that all electronic devices in my household that also tell time eventually lag behind, except the ones that get synchronized by radio signal or internet. Most of them are battery-powered, except my alarm clock (which runs slow as well). Why does none of them run too fast? Deliberate design (why)? Wrong temperature for quartz crystal? Decreasing battery voltage? Or just a coincidence?
