If indeed the friction coefficient is independent of surface area, then when I tilt them they should start to slide roughly at the same Angle.
若摩擦系数真的，与接触面积没有关系，那么两者下滑时的角度，应该基本相当。
I'll give you the Angle and I want you to calculate that friction coefficient.
我会读出角度，你们帮我计算摩擦系数。
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
