@AlephZero: All that is known about the structure is that it's thin-walled, the radius, yield strength and values for F and M are known as well... There is no information about how (or if) it's restrained. The thickness of the walls is the thickness of the circle, the thickness of the black...
the moment arrow represents the axis around which the moment is acting. Using the right-hand rule, one can see that the left must be in tension and the right in compression.
Okay, I redrew the whole thing, now with correct axes.
Here I already split the force in a force in the centroid and a moment around the centroid. My question is: How do I find the maximum stress in this cross section? Where is it going to fail first? I want to know how thick my walls...
Thanks for all your help! No doubt I understand buckling better now. Thanks in particular to SteamKing, your link has provided me with the necessary tools (buckling with eccentric loads can provide a specific amount of displacement). Thanks AlephZero for your help as well, but unfortunately I'm...
wow, okay. I thought as much when I was looking at my books, not a single example of a calculated displacement. But is it possible to counteract the buckling effect? Like applying your compressive force off centre so that there is an induced moment which counteracts the displacement due to...
Hi there,
I was wondering how one can calculate the displacement due to buckling. I already checked the general displacement calculations, but they didn't amount to anything.
So a simply supported beam under compression.
Thanks!
And what about the stresses? I can imagine that the left side of the cross section is experiencing more stress in this case than if the torque would be applied in the center.
I know that if a force is applied off center (as in: not in the center of gravity), one can split them up in an equal force and a moment in/about the center of gravity. But what about a torque applied offcenter?
Maybe this image clarifies my problem:
So the force will be split op in a...
