单词 spring
释义

spring

A device, usually made out of wire in the form of a helix, that can be extended and compressed. It is elastic and so resumes its natural length when the forces applied to extend or compress it are removed. How the tension in the spring varies with the extension may be complicated. In the simplest mathematical model, it is assumed that Hooke's law holds, so that the tension is proportional to the extension.
