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。
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.
所以只有当,摩擦力,小于或等于最大值的,时候才不会倒。
So now the situation is only safe as long as the frictional force is smaller or equal to the maximum value possible.
物体运动，并向上加速度，因为摩擦力方向斜上，值为这个。
It is moving, so sure, it's going to be accelerated so the frictional force is in this direction, has this value.
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?
针对这一问题，本文研究了零件加工误差对动模板合模位置的影响，得出了零件加工误差的许用值范围，并计算了由于销轴摩擦力对合模力放大比的影响关系式。
Aiming at these problems, this paper studies how the original error affects the accuracy, works out its allowable values, and finds out the equation between friction of pins and clamping force.
结果表明，剪力盒壁摩擦力将会影响试验土样中的应力分布和剪切面上的正压应力值。
The results show that the frictions caused by the wall of shear box will influence the distributions of stresses in specimens and the normal pressure stresses on the shear plane.
地震动态应力使围压产生低值波动，一方面使围压减小、摩擦力减小；
