AI Thread Summary
To calculate the maximum flexural stress in a cast iron pipe under a point load, the relevant equation is M/I = σ/y, where M is the bending moment, I is the moment of inertia, σ is the stress, and y is the distance from the neutral axis. The pipe's dimensions include an external diameter of 60mm, a thickness of 10mm, and a length of 5m, with a point load of 100N applied at the center. To find the bending moment, further research on basic flexure theory and bending moment calculations is necessary. Resources such as textbooks or specific online references can provide guidance on applying these concepts. Understanding these principles is crucial for solving the problem effectively.

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.
