[TOMT][Video] Youtube Educational Video showing how to do a specific Dynamic Systems Problem

For the past hour I've been trying to find a video that I watched literally four hours ago.

For those familiar with dynamic systems, it's a Youtube video depicting a how to model a Rotational Dynamic System.

The problem in question is a gas pedal with a spring connecting the cantilever (beam) portion to the ground of the car.

I have tried searching all kinds of words in the Youtube search and looking beyond the 10th page and for the love of God cannot find it again. I'm usually good at finding the things I need to find so this would be a huge help if someone knew the video!
