My chum Charles Pfeil just sent me an email saying, “I think you will like this!” I must admit that I was hoping he’d discovered some way to teleport a bacon sandwich via the internet because I’m feeling a tad peckish. Instead, he included a link to this video, which took (what I laughingly call) my mind away from bacon (which is no easy task, let me tell you).

I don’t know about you, but I think that this video is awesome. It offers a simple visual way to illustrate all sorts of concepts — limiting friction, normal reaction, force direction, turning moment, center-of-gravity, etc. — along with techniques to overcome each issue as it arises.

I hear there are a lot of videos of this ilk out there on YouTube. Have you seen any of them? Do they beat this one? Which is your favorite?
