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?

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？

So that means that N of P must be in magnitude the same as the frictional force.

这意味着PN必须,在大小上,与摩擦力相同。
