WebInertial force, as the name implies is the force due to the momentum of the fluid. This is usually expressed in the momentum equation by the term ρ(du/dt) or (ρv)v. WebShape also makes a difference when finding the MOI. The general formula for mass MOI is I=Mk^2, where M is the mass of the object and k is the distance between the rotational axis and the radius of gyration. For calculating the mass moment of inertia for more complex objects, the summation of all the point masses of the piece gives the mass MOI.
