Calculating Shear Stress from Shear Flow for Scientists

Click For Summary
SUMMARY

This discussion focuses on calculating shear stress from shear flow, specifically in the context of beam analysis. Participants emphasize the importance of comparing calculated shear stress with the shear strength of the beam material to determine load capacity. Recommendations include consulting texts such as "Mechanics of Materials" and "Machine Design" for comprehensive understanding. The conversation highlights the necessity of conducting thorough research and asking specific questions to facilitate effective learning.

PREREQUISITES
  • Understanding of shear flow and shear stress concepts
  • Familiarity with beam analysis and shear force diagrams
  • Knowledge of material shear strength
  • Basic research skills for finding academic resources
NEXT STEPS
  • Study "Mechanics of Materials" for in-depth knowledge on shear stress calculations
  • Explore "Machine Design" for practical applications of shear flow in engineering
  • Learn how to interpret shear force diagrams effectively
  • Research online databases for academic papers on shear stress and flow
USEFUL FOR

Engineers, students in mechanical or civil engineering, and anyone involved in structural analysis or material strength evaluation will benefit from this discussion.

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.
