    The equation is a=(w^2)*r where a is the acceleration, w is the angular velocity and r is the radius.
    First we must convert RPM to radians per second. There is 2(pi) radians per revolution and 60 seconds in a minute. So 10,000 RPM equals (10000*2(pi))/60, which rounds to 1047. We then simply enter these values into the equation. For our first calculation on space station v we get a=(1047)^2*0.455=498,775 m/s^2
    Acceleration due to gravity equals 9.8 m/s^2, so if we divide our answer by that we can see that it is 50,895 times the acceleration due to gravity.

    Thanks to my buds at Skillshare for continually supporting this channel, I genuinely enjoy giving these ad reads and potential giving you all the opportunity to learn new skills. 2 month free trial with this link: Think I will use the site to learn guitar during my Christmas break, or maybe I'll learn how to pronounce car correctly.

      @David Kurtz both are correct, it just depends on whether you are using American English or just English. And it's unbearable, not unbareable.

      Calling america the civilised world is an insult to civilisation, you are the single most violent country that has ever existed, you have the highest prisoner to population ratio on earth, the worst education of any developed country, and your presedents are a list of psychopath murdreres, morons and what ever the hell trump is meant to be other than the most embarrassing leader a country has had since george waved at stevie wonder bush, and your constant lies and bullshit about why you constantly need to bomb countries with cold war era technology, your not civilised, you are the biggest bunch of obese terrorist morons that ever existed and you will be remembered as an embarrassment and an example of how wrong a culture could get it, in short go fuck yourself and i will buy an american flag to piss on and think of your channle while im doing it, fuck you and fuck everyone that likes you.

      A civilized world would have invited the US to the first Metric Convention, but nope the US was below them.
      Present day the descendants of the invited countries are full of misguided salt.

    There isn't a tyre which can withstand the pressure and would peel away from the hub ,then just go to the mech and later to the club.

    Hope you got my point

    The new record they are going for is...
    1000 mph.
    Seems like a nice round even number.
    But the "civilized" world calls it 1609km/hour.
    I wonder why the bench is 1000 mph and not the more attainable 1500km.

    Rolls-Royce jet engine manufacturer produces compressor and turbine discs under similar demands and technics but also use exotic materials and design to withstand high temperatures and the " hoop" stresses trying to explode the discs and high rpm and temperatures. The Bloodhound wheels look like jet engine discs prior to machining for blades.

    I don't appreciate your distinction comment that the 'civilized world' uses kilometer for measurement. Kilo and miles are both scientifically based measurements of distance by humans in different locations on the same planet. Didn't Hitler use kilometers? What about Osama bin Ladin? Kim Jong-il? Saddam Hussein? Stalin?...all used the kilo. Please don't take something as pure as science or mathematics and compare human civility to its proper use or function. Thumbs down for this one.
