 OUTPUT PARAMETERS Parameter Symbol Value Unit Mass moment of inertia about X axis Ix --- g*mm^2 kg*m^2 lb*in^2 Mass moment of inertia about Y axis Iy --- Mass moment of inertia about Z axis Iz ---

##### Definitions:

Mass Moment of Inertia: A measure of an object's resistance to rotational velocity about an axis.

##### List of Equations:

 Parameter/Condition Symbol Equation Mass moment of inertia about x axis Ix Ix= (m/12) * (3r2+h2) Mass moment of inertia about y axis Iy Iy= (m/12) * (3r2+h2) Mass moment of inertia about z axis Iz Iz= (mr2)/2
