The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due to the shape of the cross-section. It is a key parameter for the ...

the overall area of the section, A, and the way the material is distributed about an axis of interest - the geometric moment of inertia (or second moment of area) I. The shape factors for bending and ...

The BSI is the product of volumetric cortical bone mineral density (BMD) and cross sectional moment of inertia within a region of interest. Calculations combine dual energy x ray absorptiometry and ...
