Apply enough force, though, and you will go past what is known as the elastic limit and the object will be deformed permanently.

但如果向它施加足够大的拉力，超过了它的弹性极限，该物体就会永久变形。

And then, when you keep adding force — which we will do by gravity, - we will just hang weights on it — then it starts to bend over, up to a point here which we call the elastic limit.

然后，继续增加力-，受到重力的影响，不断给它悬挂重量-，然后它开始弯折，到这里的某一点，我们称之为弹性极限。

Elastic statics mainly relates to the connection between force and transmogrification, elastic body's invalidation, the guide line of design in invalidation.

弹性静力学主要涉及力和变形之间的物性关系，以及弹性体的失效、与失效有关的设计准则。
