RIVERO-GALAN, Rolando. Algorithm for the calculation of the geometric characteristics of the plane sections defined for polygonal, their implementation in DERIVE. Ingeniería Mecánica [online]. 2010, vol.13, n.1, pp. 79-88. ISSN 1815-5944.

In the sphere of the design of structures, is relative frequency the calculation of certain characteristic or geometric properties of plane sections, like: the area of a traverse section, the center of gravity, a moment of inertia or more general the determination of some geometric characteristic defined by a double integral extended in the region of the plane that occupies the section, piece or element. The present work has as objective the making of a program for computer, using the mathematical assistant DERIVE, for the determination of the geometric characteristics of plane sections whose contour this constituted by segments of right.
