在弹性限度以内,物体受外力的作用而产生的形变与所受的外力成正比。形变随力作用的方向不同而异,使物体延伸的力称“拉力”或“张力”。(推力、拉力、提力、压力、浮力统称为:拉力)
n. pull ; tension ; tensile force
琴弦 琴弦由共鸣箱穿出,再固定到颈部上的铁栓(pin)。把所有调好音的琴弦加起来,它们的拉力(tension)是730公斤。(这是为什么弹竖琴会起水泡又长茧的原因。

长期以来,拉力机制一直受到大多数科学家的青睐。
The pull mechanism has long been favored by most scientists.
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
Then, you may have forces to the right, forces to the left pushing, pulling.
