Polares Flächenträgheitsmoment
Polar area moment of inertia
Description:
In the case of a component with a circular cross-section, the torsional moment of inertia is equivalent to thepolar area moment of inertia . The polar area moment of inertia is a measure of the resistance to torsion of closed annulus and circular cross-sections. The polar area moment of inertia is the sum of the and components of the area moment of inertia and, unlike the axial area moments of inertia, can also be negative.
