The Versatility of the Mechanical Linkage || Presentation for University Dynamics Course

Linkages are beautiful. :)
Come vibe with me! I'd love some company and don't bite, believe me. :P / discord

Corrections:
1:49 I'm saying this as if these detectors are some box that you can pick up and place down somewhere which is a very personification thing of me to do... these detectors are actually over five kilometers in length. Also, this part contains napkin math! I don't have a proper source for this and made a lot of assumptions. I don't have the calculations with me anymore given I never bothered to save it, but if someone wants to verify if this is actually true or not, let me know!!
2:49 - I have not actually checked if the Roberts linkage was actually ever implemented into the system at AIGO, or if it was just one of the methods they considered and did research on. For more information on other methods being used for performing this extreme degree of precision, you can check out LIGO's website: www.ligo.caltech.edu/page/vib...
4:54 - By technicality, these are not the same linkage. Note that the output P on the 2D Roberts linkage is actually in line with the grounded points, while the TMD used in Taipei 101 actually behaves more like a parallelogram linkage, with the output payload being far below the grounded points.
5:21 - Only partially true. Yes, from the inside, the payload does "sway" to help stabilize the structure, but this sway is actually a reactive behavior to the structure swaying as well. Given the mass is not rigidly connected, as the building sways, it doesn't move along with it immediately, this is what makes it appear to shift in the opposite direction for viewers. I also never mentioned this during the presentation but the "pistons" attached to the bottom of the mass are dashpots (more colloquially called "dampers"), as to prevent the TMD from channeling all of the kinetic energy it absorbs back into the building itself.
These are all the corrections I know about. If you know of any others, let me know!

You'd think I'd be smarter about this and use PowerPoint to create my presentation or something for such a tight deadline. But nah, of course I had to challenge myself more than I needed to. My experience in Line Rider syncing really came in handy for doing a live talk over a video. :)

one of the reasons im happy ive subbed to the alternate channel

[@BeardedMan8319]

The face reveal we've all been waiting for.

[@ukiarcticfox]

with only 24 hours too, damn
you did well, you better've gotten some good marks on that

I thought I recognised 3Blue1Brown's animation! Thanks for the great video Arglin. I did find the audio a little hard to hear in places, maybe a little lapel mic might help in future so we don't miss any of your great information.

[@ArglinV3]

That's definitely of consideration!
I actually only thought of recording myself about five minutes before I had to present, so even though I don't have a lapel mic I would've probably at least brought another device along to record closer to me.
Though I wonder what my classmates would've thought seeing me mic-ed up for a far-from-formal project. XD
For the meanwhile though, the subtitles are the best I could supply, sorry!

I really liked the presentation Arglin! You present very well and I think using manim for visuals was a very good choice.

[@MrRitzyVlogs]

Great video!

[@MrNoahMango]

Awesome video, i wonder what linkages this time machine uses... (Palfly dont do it)

[@smada505]

Second! Great Video

[@Tetril_Homefiesta]

wait arglin
is that you in the video at the end
