The Mass Moment of Inertia of a body is a property that measuresthe resistance of the body to angular acceleration
The Parallel-Axis Theorem is I = IG +md2
The resultant (summation) moment about the mass center due toall the external forces is equal to the moment of inertia aboutcenter of mass times the angular velocity of the body.
Mathematically, three equations with four unknowns cannot besolved.
The kinetic energy of a rigid body can be expressed as the sumof its translational and rotational kinetic energies.
To find the kinetic energy of a rigid body with PureTranslation, the rotational kinetic energy is not zero.
Reactions at fixed supports do no work because the displacementat their point of application is zero.
