Moments of Inertia
The inertia of each geometry can be measured directly via TA Instruments rheology software. Below is a table
that shows the approximate inertia values for cone and plate and parallel plate systems. You are advised to
use the automatic inertia measurement feature in the software. (See the online help for information).
