ANGLE WITH UNEQUAL LEGS  SECTION PROPERTIES CALCULATOR
Section properties of angle with unequal legs are calculated by following calculator. Area, distances from the centroidal axes to the back of the legs,
second moment of area and radius of gyration about the centroidal axes are calculated section properties.
Section properties formulas for angle with unequal legs are given in the "List of Equations"
section.

Definitions:
Second Moment of Area: The
capacity of a crosssection 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.
