双语例句
- And as I increase the tilt this frictional force will get larger and larger and larger and then there comes a time that the object will start to slide.
随着倾斜度的变大，摩擦力，会越来越大，加到某一程度，物体会开始下滑。 - It is moving, so sure, it's going to be accelerated so the frictional force is in this direction, has this value.
物体运动，并向上加速度，因为摩擦力方向斜上，值为这个。 - For sliding contact, the coefficient of kinetic friction Uk is defined as the ratio of the frictional force to the normal force.

当摩擦力和mgsinθ，完全相等的时候。 - The object will not be accelerated and the frictional force is going to adjust along the x direction so that the acceleration indeed is zero.
物体没有加速，摩擦力会沿x方向，调节自身大小，这样和速度为零。 - 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。 - So I know what the frictional force is given by this result.
由此我得到，摩擦力的大小。 - And the frictional force, in this case will adjust itself just the right way so that Newton's Second Law in the x direction will give you, for the force, a zero.
其它情况下，摩擦力会根据情况调节自身，此时在x方向上使用第二定律，合力为0就是结果。 - So there is also a frictional force.
所以这个是摩擦力。 - 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。 - But I'm only interested in the magnitude for now, so I get R times the frictional force.
我现在只对它的大小感兴趣，是R乘以摩擦力。 - Friction prevents it from doing so so there's going to be a frictional force in this direction.
摩擦力则阻碍下滑，因此存在，此方向的摩擦力。 - The coating layer is a Telfon coating layer, namely a polytetrafluoroethylene coating layer, the coating layer can reduce frictional force, which leads the cylinder wall to be more wear-resisting.
涂层为特氟龙涂层，即聚四氟乙烯涂层，涂层可以减少摩擦力，使气缸壁更加耐磨。 - In order to analyze the distribution of internal frictional force and determine the least layer number for expansion of coiler, the coiling process was studied with FEM.

摩擦力没有变，当d等于0的时候。 - How does the frictional force do that?
摩擦力是怎么做的？ - If, however, this object wants to go in this direction-which I do not know& then the frictional force has to be put in this direction.
不过如果物体有下滑的趋势，我不知道-，那么摩擦力，就会向上。 - So this frictional force is really having a rough time starting off in this direction, slowly becoming less becoming zero, changing direction, reaching the maximum and finally losing the battle.
可以看到摩擦力一直在挣扎，开始是这个方向，慢慢减少，减为零，改变方向，达到最大值，最终不敌。 - And this is my first equation, and I have as an unknown the frictional force, a and so I cannot solve for both.
这是我的第一个等式，摩擦力还是未知数，是未知数，，and，I，have，as，an，unknown，a，所以没法得出两个解。 - If that's the case, then I know that the frictional force will be in this direction and it will have reached the maximum value with the static friction coefficient.
这样的话，我们知道，摩擦力将会向下，直到达到，最大静态摩擦为止。 - And that now must be the frictional force, because NP is still the frictional force.
这肯定是摩擦力，因为NP还是摩擦力。 - And minus Ff, the frictional force, which is the component uphill, and this is my equation number two.
减去Ff，摩擦力，也就是滑坡向上的力，这是第二个等式。 - 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？ - The method of increasing frictional coefficient is properly used to predict the frictional force of designed path of later horizontal wells.

这个方向有摩擦，因为很明显，梯子会这么滑下，而摩擦力，会阻止它这么做，它会在这个方向。
