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。

Tied arch bridges don't transfer thrust forces to their supports, meaning they can sit atop piers designed primarily for vertical loads.

系杆拱桥不会将推力传递到其支架上，这意味着它们可以坐落在主要为垂直荷载设计的桥墩顶部。

More coils will soften the structure, but having too few of these coils won't have enough thrust force for the actuation effect.

更多的线圈会软化结构，但线圈太少则无法产生足够的推力来实现致动效果。

These connections are designed to  take the massive forces of the engine, both the forward thrust force and the  downward force of the engine's weight.

这些连接旨在承受发动机的巨大作用力，包括向前的推力和发动机重量的向下力。
