Dzhanibekov Effect applied to a T-Handle, GRGM1200A and EGM2008 Gravitational Models
135This video was inspired by the Nasa video of the t handle spinning in the space station. When I looked at it, I wondered if it would keep spinning if left alone. I didn't know, so I created a model of it to test with.
Every solid body inherently has three principal axes through its centre of mass, Including the moon and earth, and each of these axes has a corresponding moment of inertia.
The moment of inertia for an axis is a measurement of how difficult it is to accelerate the body on that axis.
In this video, I test the Dzhanibekov effect on a physics model of a t-handle, an amplified moon gravitational model GRGM1200A and an amplified earth gravitational model EGM2008.
Moon Gravitational Model : GRGM1200A
Earth Gravitational Model : EGM2008
