unusual facts about Moment of inertia



London moment

The GP-B gyro consists of a nearly-perfect spherical rotating mass made of fused quartz, which provides a dielectric support for a thin layer of niobium superconducting material.

Bowling ball

Materials and fabrication changes have since allowed the assembly of balls whose interior components have a much greater range of density, thereby offering a new ball choice that, in physics terms, involves the moment of inertia of a solid sphere.

Cooper Mark IV

--don't bother to fact tag this, it's simple physics: the polar moment of inertia means the Ferrari tends to change direction more reluctantly than the T12, because the Cooper's mass is nearer its Cg.--> It made its debut in at Goodwood on Easter Monday,

Statics

The concept was introduced by Leonhard Euler in his 1765 book Theoria motus corporum solidorum seu rigidorum; he discussed the moment of inertia and many related concepts, such as the principal axis of inertia.
