截面的質心,面積,一階矩,二階矩的計算
This app. determine the properties of polygonal
sections. The (x,y) coordinates of the vertices
of the polygon (which must be located entirely
within the first quadrant) are input sequentially
for a complete clockwise path around the
polygon. Holes in the cross section, which
do not intersect the boundary, may be deleted
by following a counter-clockwise path.
