# SECTIONAL PROPERTIES CALCULATOR

In stress analysis of a member such as torsion of shaft, bending of beam,
compression of a column, etc., cross sectional properties are usually used to calculate stress and displacement distributions.

Sectional properties calculators
are developed to calculate cross section area, second moment of area, section modulus, radius of gyration,
center of gravity of the cross section and mass of a beam or column for standard profile types
and geometric shapes. Profile types and geometric shapes which can be calculated with the
calculators are hollow and solid rectangle, hollow and solid shaft (circle), I,
T, C beams (channels) and wide flange I beams.

The formulas and parameters used in the calculators are given in List of Equations sections
of the calculators.
