So once again these are all balanced forces or there's no net force going on right over here.

现在考虑更多的例子。

This tie works exactly like a bowstring, balancing the arch's thrust forces with its resistance to tension.

这种系带的工作原理与弓弦完全相同，可以平衡弓的推力及其抗拉力。

Additional cables, called backstays, were connected to anchorages behind each tower to balance the horizontal forces, similar to the way suspension bridges work with their towers and abutment anchorages.

额外的缆索（称为后拉索）连接到每个塔后面的锚地，以平衡水平力，类似于悬索桥与其塔和桥台锚地的工作方式。

An object in motion can stay in motion, as long it is being acted on either by a balanced force, or (i guess) a set of forces that balance each other, or no forces at all.

运动中的物体, 只要它不受力或所受的力是平衡力或一组相互平衡的力, 它将保持运动状态.

And so, this is true. It's not just the situation where there is no forces; it could also be the situation that's it's going to stay at rest, if there are balanced forces acting on it.

所以, 这也是对的. 这不只是没有受力的情况, 也可能是物体静止不动但它却受到平衡力的作用.

I write, picking out my words, weighing and balancing the force of every syllable, calculating the minutest effects that language can produce, erasing and rewriting, and spending a whole evening over a page of manuscript.

我写作，挑出我的词，权衡和平衡每个音节的力量，计算语言可以产生的最微小的效果，擦除和重写，并在一页手稿上花费整个晚上。
