SECTION PROPERTIES (Area, Centroid, ...) - TRIAL

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.
