The chains you see under school buses are part of a system call Onspot and are used for traction control activated with the push of a button

Why the fuck did Youtube recommend this to me?

[Connor Henderson]

He's right. Modern physics now teaches centripetal force while mentioning that centrifugal force isn't 'real'. It's an apparent force, it doesn't actually exist. Ficticious/Reactive centrifugal forces are experienced behaviours as a result of centripetal force.

How is he a dumbass?

I always pictured those autochains systems like some kind of weird net gun that shot tire chains onto the tire somehow. This is a lot more sensible, but nowhere near as cool.

Do you watch auto videos, technology, or science videos? If so, there is your answer, dumbass.

[Jesse Marano]

wouldn't this only work if the tires were spinning fast enough to make the chains swing under the tire? so if you had to slow down, for traffic or a stop sign, then start moving again you'd be f'd. or if you tried to stop and your wheels locked?

[Connor Henderson]

Except it's not highschool physics, it's what is taught in vector mechanics in university. ""fictitious" by name, does not mean it is not "Real"" is a valid point, but by no means relevant. The force you experience is real, but rather than being a force on it's own is the LACK of the real force that you're experiencing in your reference frame. Have fun!

I thought those were truck pubes.

*sigh* How did I get here this time?

[Haklangr]

No, you.
