Purpose: Illustrate the three principal axes of a thin aluminum plate.
Description: An aluminum plate is used as a pendulum which can oscillate about either of the three principal axes. The moments of inertia are: I(x)=mb^2/3, I(y)=ma^2/3, and I(z)
(x)+I(y)=m(a^2+b^2)/3, where a is the shorter side of the plate and b is the longer side. For this demonstration m=374g, a=20cm, and b=28.2cm.
Availability: Available
