First frame isa centrifuge that spins samples at high speed to separate the components in them (I think that’s the purpose, not a scientist).

I hear that if it’s unbalanced, bad things happen, because you’re not spinning an unbalanced rotor at high speeds.

I honestly was coming to check the comments to see if anyone had experience with it so I could ask how bad it is.

The centrifuge would not run like that, it noticed the vibrations and turns off. They had that “feature” for decades now.

  That’s awesome… And also funny that it had to be added. Thanks for the info!
  
  I still want to know what happens on an old one without vibration detection or if it was “broken”. I assume something like an unbalanced washing machine but on a smaller scale? It just going out for a stroll :)

    Science is a whole lot of adjusting after someone died. Like, it’s mostly been that.

    Oh that can absolutely end in a desaster. Like not breaking when driving a car when you absolutely should.

The funeral depicted is a viral video where the pallbearers are dancing/swaying so it’s like you’ll die and even your casket will be moving afterwards.

I work in a lab. I’ve seen centrifuges try to walk off the counter before.

It depends on the speed and size of the centrifuge, the mass of the load, and the magnitude of the imbalance. Someone else mentioned an ultracentrifuge, typically a large, washing-machine-like device that can spin larger loads at high velocity. The amount of energy released if they become significantly unbalanced is pretty huge: they have a containment layer, but some could kill you if the load got through and hit you.

On the flip side, I may have intentionally ran unbalanced microcentrifuges a few (many, it was many) times as a grad student because I was too tired and lazy to make a counterweight. I just held it down with fairly firm pressure and it was fine. That’s not very good for its bearings, though. Sorry lab manager!

I’m not sure about the more classic devices but a lot of game controllers and phones these days use linear motors or similar piezoelectric devices for vibration. For instance Apple’s “Taptic Engine”.
