Pinning axis is wrong

Hey, interesting experiment & cool to see some tests in different materials that aren’t at many kN load! I know this video is 4 years old, but for anyone else who stumbles across it, there is a point that was missed: You said the material in the last two tests should have failed in the direction that the pins allow - but it is important that the moment of inertia is totally different in that axis, and much higher. So while the fixed-pinned failure would be at a power load in that axis, it’s still many times times higher than the other axis that acts as fixed-fixed.

What material is used instead of steel in this video

I can't stop being curious about the material actually.

hiiii, i was just curious what interface u used?!?

Thanks

So less voice!

Thanks, this video fed my curiousssssity!

This is great. You can learn so much by designing an experiment. If you truly want to compare fixed versus pinned your pin should be at right angles to the side with the smallest I. Your brackets are not allowing the end of the pinned joint to rotate freely. Furthermore the fixed setup should clamp tightly on the end of the column (for the best results).

This is a cool video! Nice job!

excelent . but the sound volume of video is very slow

The pinned ends should be able to rotate freely. Therefore, you should better place the column top end in to a V shaped groove.

Just out of curiosity what was your score for Criterion C

what is the specimen young's modulus is it standard or you calculate by some sensor my project is attaching sensor on buckling failure setup

hi i am working on some project i need this setup how to made it and what is the specimen which you use please soon mail me i dont have much time my deadline of submitting is very near its my mail id ys10@iitbbs.ac.in thanks

Nicely explained
