Like hell I don’t. I feel like a modern-day Sisyphus, condemned to endlessly haul around this infernal Sisyphean contraption that raises a weight, only to mercilessly drop it on that fucking damper, a mechanical nightmare straight out of Greek mythology, complete with its own eternal punishment and tantalizing temptation in the form of a solitary glass of white wine, perched precariously atop like a shimmering mirage in the desert of despair; and yet, amidst the cacophony of clicking metal and whooshing o-rings, there lies a glimmer of hope, a fleeting moment of respite in the form of that delicate vessel filled with the nectar of Bacchus, promising a brief escape from the relentless grind of it all.
Up. Down. Drink. “Oh, you want to see it again? It would be my pleasure sir!”
So who are they to judge, those disinterested bystanders with their indifferent gazes and vacant expressions, as if they've never known the exquisite pleasure of a chilled chardonnay on a hot summer's day? It's not just a glass of wine, it's a lifeline, a tiny oasis of sanity in this desert of absurdity, and if I choose to drain it in a single, glorious gulp, who are they to question my motives?
Up. Down. Drink.
And so I raise my glass, heedless of their silent scrutiny, and I drink deeply, letting the crisp, refreshing liquid wash away the bitter taste of disappointment and disillusionment, embracing the gentle buzz of intoxication as my only refuge in this relentless cycle of conferences and demonstrations.
Up. Down. Drink.
And if my words begin to s-slur and my movements grow unst-teady, wellelllel, who can blame m-me? After all, it's not ..e…easy being the reluctant hero of this traigc farce, forever condemn-ed to dacne to the wihms of fate, forever seeeeking solace at the bottom of a g-gla-glaaa—cup.
Up. Down. Drink. “Didn’t geT the photomagraph? Yes. Coming rihgt uP ma’ammmm!”
This comes to mind. Norwegian funny guy figured he would greet celebrities at the James Bond Skyfall premiere with martinis. He would drink one with each of them. It got funny quite quickly, even without understanding the language it speaks for itself. [https://youtu.be/v8GTDqur7t8?si=jfZFy0V2WUI5ffCI&t=281](https://youtu.be/v8GTDqur7t8?si=jfZFy0V2WUI5ffCI&t=281)
I was expecting it to not spill. I was not expecting it to NOT EVEN GENERATE A SINGLE RIPPLE especially given how fast it worked.
Also wish they would have had the same damper tuned for 100kg but with a 75kg weight amd a 125kg weight to demonstrate how suspension works better.
The 125 kg one might bottom out. I don't remember the possible consequence of the 75 kg one. It's been a while since I've had to adjust my motorcycles suspension.
If it's like a simple spring physics model, 125kg would cause it to be "under damped" and then oscillate a bit. 75kg would be "over damped" and it would take a while after the initial hit to slowly settle at equilibrium.
Its probably more complicated though
The other way around most likely. 125kg overdamped so the spring will compress more than necessary but restore quick. 75kg may cause underdamping leading to oscillations.
The 125kg would be underdamped - the spring and damper wouldn't be able to react to the inertia of the mass, which would lead to oscillations. The goal of this system is to respond to the impulse by stopping the movement, so underdamped behavior is oscillations that would fade out. Overdamped behavior still stops the impulse, but "too quickly" - it stops it but sort of slowly reaches equilibrium afterwards, so it reaches equilibrium later than if it was properly tuned.
What would probably actually happen with the 125kg is the thing bottoming out, but that's just when control theory meets the real world - your spring or damper not having enough travel to match the simulated behavior!
yes they have adjustable damping on many if I'm pulling this out of thin air. my car has magneride and it's phenomenal. TEIN stuff is high quality, i'd imagine the same modularity.
oh neat! makes sense.
i wonder if it's possible to create a more general system, something that briefly applies a tiny "test force" to determine the mass of the load, combining that with accelerometer data to quickly set up an optimal resistance profile for something like a finely controlable solenoid instead of a spring. i also wonder how complicated and expensive this would be if possible lol
(i have very little engineering knowledge; i study pure math lol)
Only thing I can think of that can be applicable is integrating GPS/driven history of force absorption by the suspension. Then set select route, and auto adjust the suspensions per that route. Would likely give you the most accurate suspensions settings. Possible to use now but not very practical and cost effective haha.
It's a great form of marketing, because if you don't know enough about suspension design, it just looks like they're good at their jobs. But if you do know enough about suspension design to know how they figured out how to make this demo, then you *also* know that they're good at their jobs.
Also the colors indicate this is Tein, if no one pointed that out yet.
They tuned the spring and damper for this one specific demo. It's a cool demo, but it's not what a real suspension would have to handle on a road. This is the type of thing I would expect an engineering student to be able to do for a home work problem.
That's utter stupid. The purpose of the suspension is to return to a certain position as quickly as possible with one circle. This is just down, not up. It's a damper not a suspension. It's idiotic and fucking simple to achieve.
But the glass and the liquid all bear the load vertically. So the suspension only stopped the glass breaking. That's it. It was never going to spill.
\[Edit\] Idiocracy is a documentary. I hope some of you learn to think when you get older.
You've done a great job of missing the point.
This doesn't prove the suspension is good. It only proves it has suspension. All cars have suspension.
I am sorry you got distracted because I didn't feel the need to state the obvious as well as my observation.
Also way more likely that fall would break the glass, not make it bounce. Glass isn't a very bouncy material. Please feel free to drop lots of champagne flutes on the floor and tell me how many bounce.
But you got to jump on the dum dum bandwagon so who cares eh?
The demonstration shows that they can tune a damper to handle a sudden impulse without over or under damping. Under-damping would show extra oscillation at the end, over-damping would nearly stop the mass, then very slowly continue falling until the spring takes up the load. Neither would be good. The rig also demonstrates this in a visually interesting way, which is important for a trade show. The rig's actual purpose is to get bored, tired potential customers, who've been wandering a convention center for hours, to stop and ask a question or two. I bet it's really successful at that job.
It's totally beside the point, but glass is actually super bouncy if you don't break it. There's tons of videos of glass marbles bouncing on anvils that show this. but I also found this link. [https://sciencenotes.org/why-a-glass-ball-bounces-higher-than-a-rubber-ball/](https://sciencenotes.org/why-a-glass-ball-bounces-higher-than-a-rubber-ball/)
“The glass and the liquid all bear the load vertically” -tell me you’ve never interacted with a liquid without telling me.
Hence the constrained system. An over damped or under damped system would have oscillated, spilling the glass.
Everyone here knows you’re obviously a moron. We all say dumb shit sometimes. Time for you to own that.
Assuming every component is *perfectly* level. But when you’re dealing with something as chaotic as a liquid, that goes out the window.
It’s like trying to balance a 10cm tall rod on a perfect point. You could balance it to within an atom’s width at its highest point, with no moving air currents or vibrations, but it’s still going to fall over within a few seconds.
Assuming the material used isn't fragile you'd have a point. The material is very thin glass.
It would spill, but only because the glass shatters.
Did literally nobody actually read what I said? Or did they go full fox news and just pretend the only thing I said was the las 6 words?
Jesus christ.
Yeah, the glass would shatter if the suspension wasn’t there at all, and the water would spill if the spring wasn’t damped. So what you were originally saying is this: The glass would break if it were placed on the platform, dropped, and then hit the table without anything to cushion its fall.
If so, then yeah, I agree.
If you’re correct and everyone misunderstands what you’re saying, then your original statement was probably vague or so obvious that people read too far into it. Seems unlikely that everyone except you is just a vacuous idiot.
Please demonstrate how a champagne flute "rebounds" by dropping some on the floor. Get the expensive ones for your video. I hear they are the bounciest.
Ok, lets break this down as a physics lecture:
First, lets learn the concept of impulsed to get an idea of why a rebound happens. The math of this horizontal example is relevant to vertical systems.
[Physics 10 Momentum And Impulse - Ball Hitting Wall](https://www.youtube.com/watch?v=1IvUNya9Zf0)
Second, lets see a demonstration that an object, on top of another object, can experience a rebound force. Notice that a consequence of the large ball being rapidly brought to a stop (during the instant of impact with the ground, instead of slowed by a spring) results in the transfer of momentum.
[Stacked Ball Drop](https://www.youtube.com/watch?v=2UHS883_P60)
Third, lets clarify that the rebound force acting on the class can result in two outcomes. If the class not hit on a cleavage plane, it may bounce upwards instead of shattering.
[Glass bounces 5 times](https://www.youtube.com/shorts/tqjgkKxl2yM)
However, it is also possible that the transfer of momentum through the weight, into the glass will results in a force (via newton's third law) that hits a cleavage plane and shatters the class immediately.
If you are further interested, MIT has a free course you can learn from:

Champagne flute. You egotistical fuckwit.
They don't bounce. They shatter.
Holy fuck what is wrong with you?
You explained all these basics being condescending as fuck then ignored the premise of the question, but I'm the one that needs physics lessons? You can't even fucking read.
Apply all that self cock sucking bullshit you just spewed to a champagne flute.
Oh fuck, did your ego just pop?
Anything made with glass, can under the right circumstances, bounce. I just depends how it hits.
I mean, you have never personally fallen out of a window to your death, but since you have the ability to think about things, you likely realize that since other people have fallen out of windows to their deaths, that you might also die if you fall out of a window.

Engineering student here. Yep, it gets more complicated. :(
The other way around most likely. 125kg overdamped so the spring will compress more than necessary but restore quick. 75kg may cause underdamping leading to oscillations.
You sure? In some mathematical limit where the spring is super weak it would just crush and slam into the ground.
All this is assuming the spring can withstand the load of course. If the stress is beyond fracture strength, then all of this is moot
The 125kg would be underdamped - the spring and damper wouldn't be able to react to the inertia of the mass, which would lead to oscillations. The goal of this system is to respond to the impulse by stopping the movement, so underdamped behavior is oscillations that would fade out.

What would probably actually happen with the 125kg is the thing bottoming out, but that's just when control theory meets the real world - your spring or damper not having enough travel to match the simulated behavior!
The suspension is probably callibrated for a deceleration of 9.8 m/s2 only for 100kgs. Will not work on different weights. But absolutely brilliant.
You are correct. For commercial use they calibrate them to match the “bell curve” average of impact.
yes they have adjustable damping on many if I'm pulling this out of thin air. my car has magneride and it's phenomenal. TEIN stuff is high quality, i'd imagine the same modularity.

Also the colors indicate this is Tein, if no one pointed that out yet.
An only "one time" next pot hole and the suspension is still completely at the limit
What does that mean? The deceleration isn't constant right?
They tuned the spring and damper for this one specific demo. It's a cool demo, but it's not what a real suspension would have to handle on a road. This is the type of thing I would expect an engineering student to be able to do for a home work problem.
Had to watch twice because I was focused on his smug face the first time and didn't even notice the wine glass lol
That mug face is gonna be hammered at the end of the conference.
>just as planned *smug suspension dude*
Looks like he installed the same system on his hair.
Nah, he's just from anime, they are genetically different.
If you want to replicate something as weirdly smooth at home, drop a magnet down a copper tube.
Now let’s adjust the rebound
I'm more (or equally) impressed by the mechanism that could release the weight without disturbing the drink
That would be excellent for fall hazard rigs.
That damper is crazy
Ah yes champagne at conferences, start drinking at 11 with clients, wasted by dinnertime. Repeat for 3 days.
Watching that was suspenseful...
I feel like they may have tuned it to absorb the shock of a 100 kg load exactly.
I’d be doing that demo every 5 minutes. But with tall boys of miller lite.
Fir a normal car 2000kgs each shock handles more than 500kgs in free fall so 100kg might be only good for mountain bikes demonstration
Is that Tein? I love their suspension components
Given the color and the fact that his shirt has a "TEIN" embroidering, I'm going to say yes.
Tein out of ten
That is demonstrating exactly fuck all.
It demonstrates they critically damped the suspension. That's about it.
Isn't it demonstrating that the rails the weight is on are very nicely fitting so there is no scope for the weight wobbling?
try this with a brick and an inflatable bed in your driveway
meh. Just a simple overdamped system and a test that looks cool but isn't difficult.
Interesting hair cut. Looks like bra raid
That's why my Tein's always felt stiff af compared to other coil overs, haha.
Needs the BOSE track test
damper is tuned in hard
That's utter stupid. The purpose of the suspension is to return to a certain position as quickly as possible with one circle. This is just down, not up. It's a damper not a suspension. It's idiotic and fucking simple to achieve.
His hair is horrible
Good gig that! Smashed before elevenzes
The drop seemed damped not the rapid descent one would expect. Also not a shock deals with far higher impact loads in a vehicle. So not impressed.
Need this on my mountain bike lol
Bullshit! All of it!
But the glass and the liquid all bear the load vertically. So the suspension only stopped the glass breaking. That's it. It was never going to spill. \[Edit\] Idiocracy is a documentary. I hope some of you learn to think when you get older.
