frictional force

常見例句

雙語例句

• 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,梯子會這麼滑下，而摩擦力,會阻止它這麼做，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.
