Intermediate axis theorem

Описание: This computer simulation shows an example and demonstrates "The Intermediate Axis Theorem" (also known as the "Tennis-racket Theorem"). The weird behaviour of "flip-overs" back and forth while spinning an object around its intermediate principle inertia axis as oposed to the stable spinning around its maximum principle axis (most stable) and minimum principle axis. I was inspired by Vertasium's video "The Bizarre Behavior of Rotating Bodies" to do this computer simulation. I was surprized that an idealized simulation with no other boundary conditions than the initial force couple to initiate the spinning actually captured the effect without introducing any minor unstabilizing force to get it going...
