How does Hydraulic Press stop so fast after shaterring something? Why isn’t there any momentum?
In: 5397
Unlike gases like air, liquids like water and hydraulic oil tend to not change their overall size (volume) that easily.
When you have a lot of gas squished in one container, it’s as if you had a rubber band stretched out, ready to go flying when released. Since liquids can’t be squished as easily, when more liquid gets added in it just tries to push everything else out of the way, which is what happens in a hydraulic press. When nothing is in its way then it has nothing to push against, which is why it can stop itself rather easily simply by stopping more liquid flow in, whereas compressed gas has to get all the gas out in order to have all its energy released.
