Find beam stress in a beam with varying cross section

AI Thread Summary
To calculate stresses in a beam with a varying cross-section, standard methods exist for analyzing such beams, but specific details about the problem are crucial. The discussion highlights the need for a 3D sketch of the entire assembly, including the beam and any components like wheels, to better understand the forces involved. Reference materials such as Timoshenko or Megson are recommended for further learning. The user is encouraged to explore these resources and provide more information about the beam's design. Understanding the transition between different cross-sections is essential for accurate stress analysis.

Homework Statement


Hi, I'm trying to figure out how to calculate the stresses in my beam. The cross section varies (shown in the picture), and I don't know how I'm supposed to think to find the maximum stress. I appreciate tips or links to learn how to do it. Thanks. Sorry if the picture is bad, but I hope you understand what I mean.

There are standard methods for dealing with variable section beams . Have you done any research online or looked in any standard reference books such as Timoshenko or Megson ?

What are the full details of the actual problem that you are dealing with ?

Hi, the problem is to design a beam by myself. I don't have any spesific dimensions. The problem is that I don't know how to deal with it when it goes from one cross section to another. I have tried to look it up on online, but didn't find anything. I just know that it should look something like that with a hole for a wheel to roll into.

Thanks! :)
 
Try posting a 3D sketch of the whole assembly of beam , wheels and any other related components .

Something like this. The forces come from the wheel because they are supporting a weight.
