That's interesting so I guess I shouldn't be looking at buckling for these short scenarios. I have calculated all the things you mentioned and have verified it is short. I was simply looking at buckling originally because I came across something called Johnson's equation which supposedly can...

thank you i'll look at this

I see. That does make sense. Would that lead to structural failure though?

thank you!

Can a moment about the end of something cause buckling or does it need to be an applied force? For instance the uploaded image Thanks!

Homework Statement A constant electric field of magnitude E = 120 V/m points in the positive x-direction. How much work (in J) does it take to move the charge Q =11 μC from x1 = -67 m, y1 = -36 m, to x2 = 98 m, y2 = 75 m? Homework Equations You see that's the problem... I have no idea...

did you ever figure this out?

When calculating buckling force i have only found how to calculate it with a force applied to the entire cross section, how can you use Euler's if the force is applied just to an edge or point. Thanks

Hey I was wondering how you're supposed to calculate the buckling force for a short column. Is there even a way? If there is, is it accurate and how do you use it? And finally how do you know when to use it?

Thank you, you really have been a lot of help in having me understand buckling. You guys have already answered my question but if you're interested in responding please do... I was just wondering if Euler's Buckling still holds under thermal stress? From the readings I've done it seems like yes...

Thanks both of you very much. jrw66- I can usually understand these things better upon working it out a little bit. So "made" a little bar with circular cross sections on the ends. It is .2m long and the diameter is .01m. So I found the equation Fcr=[pi^2*(Modulus of Elasticity)*(second...

I was wondering if the Euler buckling method is simply theoretical or actually accurate in the real world. I am asking this both for complex structures and a simply compressed rod or beam. Thanks
