About this tool
Area, second moments, section moduli and radii of gyration for rectangle, circle, hollow and I shapes.
Rect b·h³/12; circle πd⁴/64; hollow = outer − inner; I-section flanges plus web with the parallel-axis term.
Formula: I = b·h³/12 S = I/(h/2) r = √(I/A)
Example: Shape = Rectangle, Width b (mm) = 300, Depth h (mm) = 500 → Area (cm²) = 1,500, Ix (cm⁴) = 312,500.
Geometric properties about the centroid only; no effective width, buckling or classification rules.
