Work with hinges

- [Instructor] In this video,…we take a look at strategies for designing,…engineering a realistic hinge.…Why do we do this?…Well, hinges are important any time there is a door…or opening that needs to operate.…Let's review the basic parts of a simple hinge…to better understand what they do.…Now, this first example assumes…the door and case are both flat.…We'll do a more complicated example next.…On the right side, we've got the two basic leafs…which also continue to form into these knuckles…which are connected and then there's a pin down the center.…
