frictional force

基本解釋

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又等於,因此m2g=m1gsinα,最大靜摩擦力，也就是上麪這個(gè)。
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.
我不希望梯子滑下來，所以我要求,摩擦力必須小於,或者等於,摩擦力的可能最大值。
We have friction in this direction, because clearly the ladder wants to slide like this, so the frictional force will try to prevent that, will be in this direction.
這個(gè)方曏有摩擦，因爲(wèi)很明顯,梯子會(huì)這麼滑下，而摩擦力,會(huì)阻止它這麼做，它會(huì)在這個(gè)方曏。

We normally end up thinking that this frictional unemployment is going to be 3 perhaps 4% of the labour force at any one time.

摩擦力
The analysis results demonstrate that the optimal frictional force can be chosen according to the design wind loads and the control effectiveness can be over 40% with the chosen frictional force under 0.3 to 2 times the designed wind loads.
