【 摘 要 】

The centroid, the moment of inertia, and the product of inertia for an arbitrary polygon and an arbitrary plane area, are formulated in algebraic forms and programmed with MATLAB software. Three numerical examples are shown and indicate the method can be easily computed by the computer for geometric properties of arbitrary beam sections in mechanics of materials with simply or multiply connected boundaries.
