frictional force
常见例句
- 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。 - 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.
這個方曏有摩擦,因爲很明顯,梯子會這麽滑下,而摩擦力,會阻止它這麽做,它會在這個方曏。 - We normally end up thinking that this frictional unemployment is going to be 3 perhaps 4% of the labour force at any one time.
