Discussion Overview

The discussion revolves around the concept of pressure in static fluids, focusing on its definition, visualization, and understanding. Participants seek to clarify what pressure means, particularly at a point, and request resources for better comprehension, including tutorials and illustrations.

Discussion Character

  • Conceptual clarification
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant expresses difficulty in understanding the concept of pressure and requests tutorials and images to aid comprehension.
  • Another participant suggests a general example of pressure, such as pressing down on an arm, and provides a link to an article for further reading.
  • A third participant clarifies that pressure is not defined at a single point but rather over a region, explaining that it is the total force divided by the area. They mention that if the force is constant, it can be thought of as pressure "at a point," but if it varies, a limit process is necessary.
  • The initial poster acknowledges the explanation and asks for more information on the topic.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the definition of pressure at a point, as there are differing interpretations regarding its application and understanding. The discussion remains open with various viewpoints presented.

Contextual Notes

The discussion highlights the complexity of defining pressure in static fluids, particularly regarding the assumptions about force distribution and the mathematical processes involved in understanding pressure at a point.

hello world,
We are studing about static fluids and i can't introduce the concept of pressure to my mind
I can't imagine what is pressure?What is pressure at a point?I need images and iluustrations
could you suggest for me some simple tutorials and some pages to read in order to fully imagine what is pressure?
Thanks

Are you wanting something for pressure in general, or specific for a fluid? A general example is to simply press down on your arm or to set something in your hand. For a fluid or gas the first picture in the following article seems like it might help. http://en.wikipedia.org/wiki/Pressure
 
Strictly speaking, "pressure" isn't defined at a point. The pressure on a region is the total force on that region divided by the area of the region. Of course, if the force is constant on the entire region, no matter what "sub region" we take, we would always get the same fraction and so could think of that as the pressure "at a point". If the force varies, you would have to use a "limit process" as is done in Calculus.

Thanks very much for the page,I'm checking it
