Calculating Shear Stress from Shear Flow for Scientists

Click For Summary

Discussion Overview

The discussion revolves around calculating shear stress from shear flow, particularly in the context of beam analysis and material strength. Participants explore the relationship between shear force diagrams, shear stress, and material shear strength, while also addressing challenges in finding relevant resources and understanding the concepts involved.

Discussion Character

  • Exploratory
  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant inquires about the method to calculate shear stress using shear flow.
  • Another participant suggests that understanding the maximum shear force from the shear force diagram is essential for determining the load a beam can withstand, emphasizing the need to compare this with the material's shear strength.
  • Several participants express difficulty in finding resources or links that explain the calculation process.
  • A participant proposes that shear stress can be calculated by dividing shear flow by thickness, seeking clarification on this point.
  • There are suggestions for using textbooks on Mechanics of Materials or Machine Design for more comprehensive information.

Areas of Agreement / Disagreement

The discussion reflects a lack of consensus, with participants expressing differing levels of understanding and resource availability. Some participants emphasize the importance of finding external resources, while others struggle to locate useful materials.

Contextual Notes

Participants have not provided specific assumptions or definitions regarding shear flow or shear stress, and there are unresolved questions about the calculation methods and the relationship between shear stress and material strength.

Who May Find This Useful

This discussion may be useful for students or individuals seeking to understand the relationship between shear flow and shear stress in the context of beam mechanics and material strength analysis.

TL;DR
shear flow to shear stress
how to calculate shear stress using shear flow
 
Engineering news on Phys.org
What have you found in your reading so far? Can you post some links to your reading, and ask specific questions about the parts you are having trouble understanding? Thanks.
 
im just curious when we get the maximum from the shear force diagram but how to know that that is the load that beam can withstand so we have to compare the stress with the beam material shear strength right
 
but i just can't find how to do that process
 
Get a text on Mechanics of Materials or one on Machine Design; this is a bit too much for a post.

You didn't address my post. Please post the links you have been reading, or this will be a *very* short thread...
 
i can't find any links that i can read about that, that why I came to ask here
 
Try using Google with several search terms that apply. That's an important skill to have in modern times... :wink:
 
Then you were not trying very hard, because I found several good links in less than one minute of searching. However, the suggestion by @Dr.D above is a better approach because books on the subject go into more and better detail than web sites.

Zero effort in asking a question on PF (and possibly misplaced schoolwork)
okay, can I ask the last question is shear stress can be calculated by shear flow/thickness?

Sigh. Very short thread is closed.

Please start a new thread where you actually show some effort and post links to your reading and ask specific questions about that reading that you do not understand.

Also, if this is for schoolwork, repost in the Homework Help forums, not in the general technical forums. Thank you.
