alpha angle 英/ ??lf? ???ɡl / 美/ ??lf? ???ɡl / - 1
I have here that same ladder, and now what I will do is I will set the angle alpha not exactly at the critical point but a little lower, so that when I let it go, we'll all see that it will slide. 这是一个梯子，现在我要,使得角度α,不是恰等于临界点,而是略小一些，所以当我放手，我们会看到它下滑。 - 2
The angle of alpha will then be tangential to this point. - 3
It is fairly easy to measure a friction coefficient by putting an object on an incline and by changing the angle of the incline, increasing it This is the angle alpha. 测量摩擦系数有一种简单方法,把物体放置在斜面上,然后不断增加斜面的倾斜度,这是角α
