critical speed

基本解释

And this is the critical speed, which has a 1-over-r relationship.
这是临界速度，是1>r的关系。
Well, this critical speed for a small ball bearing would be some hundred meters per second.

Now you could say, "Well, what is the meaning of this critical speed here if they never reach that speed anyhow?"
现在，你可以问，如果不可能达到那个,速度，那么临界速度,在这里的意义是什么
