This page provides a diagram and functioning calculator to compute the mass moment of inertia for a cone around it's z axis, an axis through the tip, the base and the centre of mass.
Izaxis=31mr2
Itip=m(203r2+53h2)
The following are the variables for the equations...
I = the moment of inertia (
kg/m2
).
h = the height of the cone (m).
m = the body's mass (kg).
r = distance between the centroid of the body and the axis, i.e. the radius (m).
Ibase=m(203r2+101h2)
Icentremass=m(203r2+803h2)
