D2-41: MOMENTS OF INERTIA ABOUT THREE PRINCIPAL AXES

d2-41a d2-41b

Additional Info

  • ID Code: D2-41
  • 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)=I(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.
