拉力的增加与到达它们最终点的距离成相反的比例。
The tension grew in inverse proportion to the distance from their final destination.
一旦海洋板块开始下沉,它就会受到另一种力量——板块拉力的影响。
Once the ocean plate begins to sink, it would be affected by another force—slab pull.
拉力的方向是这样的。
You cannot have a spring pulled only at one side, because then it will then accelerate with infinite acceleration in that direction.
你不可能对弹簧只施加一边的拉力,因为那样的话弹簧就会以无穷大的加速度加速,就在这个方向上
This is very important, because when you buy a rope, they will tell you how much tension it can take before it'll snap.
这非常重要,因为你去买绳子,他们会告诉你,绳子能承受的最大拉力是多少
So springs are always pushed or pulled on either side with the same force.
所以弹簧两边永远都是受到,相同的压力或拉力
