How Do You Calculate Maximum Flexural Stress in a Cast Iron Pipe?

[samuelvil]

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?

 

[samuelvil]

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.

For basic flexure theory, try this ref.:

If you don't know how to calculate the bending moment, more research will be required.
