Area Moment of Inertia - Brain Waves

Описание к видео Area Moment of Inertia - Brain Waves

So what's an area moment of inertia? It's just a number that described the portion of the stiffness of a beam due to its cross-sectional shape. I show how rotating a rectangle 90 degrees changed its area moment of inertia and I do a simple experiment. Warning: Professor trying to walk on a narrow beam.
