Moment of inertia of rectangle calculator for area moment of inertia, section modulus, cross section area and radius of gyration calculation of rectangle section.
Steel rectangular bars are covered by ASTM A108 “Standard Specification
for Steel Bar, Carbon and Alloy, ColdFinished”, A36/A36m “Standard
Specification for Carbon Structural Steel” and ASTM A276 “Standard Specification
for Stainless Steel Bars and Shapes“ standards.
