Discussion Overview

The discussion revolves around calculating the maximum flexural stress in a cast iron pipe subjected to a point load. It includes aspects of structural analysis and the application of relevant equations in a homework context.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant presents a homework problem involving a cast iron pipe with specific dimensions and a point load, seeking help on how to calculate the maximum flexural stress.
  • Another participant questions the effort put into finding resources, suggesting that the original poster should have consulted textbooks or notes from their course.
  • The original poster responds, indicating a lack of specific textbooks and expressing difficulty in finding applicable resources online, requesting advice on where to learn about flexural stress calculation.
  • A later reply provides a reference link for basic flexure theory and suggests that further research is necessary to understand how to calculate the bending moment.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best approach to solve the problem, with some expressing frustration over the original poster's efforts while others provide resources and suggestions for further research.

Contextual Notes

There is a lack of specific textbooks mentioned, and the original poster's understanding of the bending moment calculation remains unclear, indicating potential gaps in foundational knowledge.

Homework Statement


so the question I got from my teacher is:
A cast iron pipe of external diameter 60mm and 10 mm thickness and 5 m long is supported at its ends. The pipe carries a point load of 100N at its centre. Calculate the maximun flexural stress induced?


Homework Equations



I think that the relevant eqn to be used should be
M/I=σ/y=ε/r

The Attempt at a Solution


I have the equation but don't really know how to solve it as I was not able to get any example...please help

How hard did you look?

If you are taking a structural analysis course, you should have a textbook or some notes. Did you do any work at all besides log onto PF?
 
yes I did, we don't use any specific textbook, and if you do have some references it will be welcome,it is the first time I use such websites. I tried to watch some videos on youtube, and tried to have some information on google, but the explanation are so vast that I am not able to find out how to apply it to the question I have. I don't want you to do all the work...I just want an advice or a website where I can understand how flexural stress is calculated.
