摘要

Constructive element of variable inertia in the shape of a parabola of degree between 1 and 100 or more than 100 whose cross section (section by a plane perpendicular to the directrix, being the guideline, the line joining the centers of gravity of the successive cross sections of the part) has moment of inertia of area (moment of inertia of the area with respect to the axis perpendicular to the plane of the bending that is considered to pass through the center of gravity of the section, that is, the integral of the area differentials of the section multiplied by the distance to the square of said differential of area to the mentioned axis) variable following the guideline of the beam, minimum in the center of the span and maximum in the ends, being equal in both ends. As variants are described beams with more than two supports, and beams in corbel (one support). (Machine-translation by Google Translate, not legally binding)
