What is sinosoidal and helical buckling? And why do I have to think about it?

Hi. i really like the way you explain things. If I may request a topic, can you cover the mechanism of "bit walk"? you did mention it in one of your video, but I think I need a more in-depth coverage of the topic. Thank you in advance!

The helical buckling happens in the speedometer cable spun by the front left wheel in an old volkswagen. Makes the speedometer needle wiggle.

Hi, very interesting videos. I didn't recognize you last time we met in Anger's rig but I had seen your videos before.
I'm going to keep learning from you.
Best regards,
