Symbols: B = Side Dimension; T = Thickness; M = Mass per unit length; A = Cross-sectional area; I = Second moment of area; i = radius of gyration;  Wel = elastic section modulus;  Wpl = plastic section modulus;  It = Torsional inertia constant; Ct = Torsional modulus constant;  As = Superficial area per metre length

Definitions:

Second Moment of Area: The capacity of a cross-section to resist bending.

Radius of Gyration (Area): The distance from an axis at which the area of a body may be assumed to be concentrated and the second moment area of this configuration equal to the second moment area of the actual body about the same axis.

Section Modulus: The moment of inertia of the area of the cross section of a structural member divided by the distance from the center of gravity to the farthest point of the section; a measure of the flexural strength of the beam.
