m2g Now, I know what T is, that is, m2 g + so m2 g equals m1 g sine alpha plus the maximum frictional force, which is this value.

而T又等于,因此m2g=m1gsinα,最大静摩擦力，也就是上面这个。

Now, I don't want this ladder to slide, so now I have a requirement that the frictional force must be less or equal to the maximum frictional force possible.

我不希望梯子滑下来，所以我要求，摩擦力必须小于，或者等于，摩擦力的可能最大值。

youdao

So now the situation is only safe as long as the frictional force is smaller or equal to the maximum value possible.

所以只有当,摩擦力,小于或等于最大值的,时候才不会倒。

youdao

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？
