Apply enough force, though, and you will go past what is known as the elasticlimit 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 elasticlimit.
