Chewing French Fries
I am ridiculously addicted to french fries. I don't have a specific favorite place or type of fry that is the best, literally any fried rectangular potato will do for me.
I ate some french fries today, and figured why not address the physics behind me chewing my fries. You produce a different amount of force with your molars than your incisors. Men produce about 150 pounds of force with their molars and 83 with their incisors. Females can produce 108 pounds of force with their molars and 57 with their incisors. I happen to be a female, and I chew fries with my molars, so I am going to use 108 pounds of force, or 480.41 newtons.
That's alot of force for a french fry! 480 N is about how much force it would take to lift a 50 pound weight at a constant velocity. I would struggle to do that, but I can produce that much force with my jaw with little effort.
This wasn't a very in depth look at french fry physics, but this was an incredible thing to learn in my opinion.
