Question

翻译（土木工程专业英语）

Altogether，three forces can act on a structure:vertical-those that act up or down;horizontal-those that act sideways;and those that act upon it with a rotating or turning motion.Forces that act at an angle are a combination of horizontal and vertical forces.Since the structures designed by civil engineers are intended to be stationary or stable，these forces must be kept in balance.The vertical forces，for example，must be equal to each other .If a beam supports a load above，the beam itself must have sufficient strength to counterbalance that weight.The horizontal forces must also equal each other so that there is not too much thrust either to the right or to the left.And forces that might pull the structure around must be countered with forces that pull in the opposite direction.‡

Answer 1

Altogether，three力量在结构可能行动：垂直那些那次行动上上下下; 水平那些斜向一边那次行动; 并且行动在它与转动的或转动的行动的那些。行动得有一个角度的力量是水平和垂向力的组合。因为土木工程师设计的结构意欲固定式或在平衡必须保留stable，these力量。垂直的forces，例如，must互相是相等的。如果射线支持装载above，the射线必须有抵消充足的力量那重量。水平的力量必须也互相合计，以便没有太多推在右边或到左边。并且也许拉扯结构的力量必须抵抗用进站相反方向的力量。
