Understanding Inertia Using Eggs
You probably know that by spinning an egg, you can find out if it is raw or hard-boiled. But did you know that if you stop a spinning raw egg for a second with your finger and release it, it continues spinning for a little bit? A raw egg...

Why Do Tightrope Walkers Carry Long Poles when Walking on A Rope?
Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

Second Moment of Area Summary
The second moment of area (or moment of inertia of area) about the x or y axis can be found using the integral of y^2 dA and x^2 dA respectively. The larger the moment of inertia, the greater resistance to bending / rotation.

Finding angular velocity of a rotating bar using energy methods about center of mass - Method 2
The bar is purely rotating about the pin support. However, we can view this phenomenon as simultaneously rotating about the center of mass while the center of mass is moving in a circular path. This means we have to include both the...
