这意味着,摩擦力在最大值，静摩擦力因数乘以,等于mus乘以,θ，times，mg，times，the，cosine，of，theta。,什么时候会发生？

And so that means that the frictional force is a maximum value possible, N which is the static friction coefficient times N, and therefore that is mu of s mgcos And when will that happen?

随着坎合面法向预紧力的增大，坎合因数逐渐增大到一个稳定值；

As the pre-force is improved, Bumpy-ridge coefficient will increase to a steady value therefore.
