Somewhat slow explanation, but the guy gets out his blow torch to heat things up, and uses a spanner and a screw thread to demonstrate the tension stuff. I love these kind of practical demonstrations.

You have to understand that YouTube monetizes videos that are over 10 minutes long and severely penalizes videos that are under 10 minutes unless they're shorts. So after YouTube implemented that rule I don't know if you noticed but every YouTube video maker started filling the intro with fluff and started extending all the talk and chatter in their videos until they finally get to the point you watch them. They used to make videos that were 3 minutes long and you saw them and they were very informative but when YouTube put that new policy in everybody started patting their videos. That's why now I just skipped the first 3 minutes of every video if I'm in a hurry because there's never going to be anything important in the first 3 minutes and usually you can skip to the 75% length of the video and that's where you're going to see what the title was all about.
