It's an explanation about how jaws of life, the tools used to extricate people from damaged cars, work and how they are used. To my embarrassment, I'll admit that I always imagined the jaws of life to look more like jaws, perhaps on a giant tractor arm with teeth where it would normally scoop up stuff. Rationally, some corner of my brain had an inkling that a giant tractor with jaws on it couldn't possibly be useful for anything except picking up the damaged car and shaking the injured person out-- which wouldn't do the crash victim any favors. I'm glad to know that my strange imaginings are in this case grossly incorrect.
I learned another thing in reading the article-- what a hydraulic system is. Reading the article made it quite evident that I actually had no idea what a hydraulic system was-- it's just one of those things that you here in conversation or in ads or on tv so many times that you THINK you know what it means... but really you've got no idea. So I followed the link on the page and read about hydraulic systems too. This website, www.howstuffworks.com, is pretty useful.
