Find the mass moment of inertia, Izz, for the spherical ceramic femoral head ball (with a cylindrical hole) from a total hip replacement. Assume that r = 4.3 cm, and density is a uniform 6 g/cm³. (Recall that reasonable approximations around the intersection of round and flat objects are acceptable; select a simple approximation). oe A d'Entrement 2017 Femoral head ball I=14778.89 [g-cm²] T/2 [1/2

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.
