We'll give it a name, but by linking that T to that T, we can also figure out the same T must be exerted on this one by Newton's third law, because if this block is the only one that could be pulling this rope with T.
我們先給它命個名,把這個 T 和那個 T 聯(lián)系起來,利用牛頓第三定律,我們可以知道這個 T 也一定作用在這個物躰上,因爲(wèi)如果這個物躰是唯一,受到繩子拉力 T 的物躰
