The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due ...

Servomotor Measures Its Own Inertia Load. Feb. 17, 2009. ... Matt Pelletier. The moment of inertia of the load is a key measure for sizing and tuning servomotors.

Here K is the "torsional moment of area" about an axis normal to the section. For a cylinder K = pr 4 /4, and so f T = 1 for this section. The shape factors for bending and twisting are shown for ...

MOI is an acronym that stands for “moment of inertia.” This measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting.
