Calculating section modulus. It is often reported using y c where c is the distance from the neutral axis to the most extreme fiber as seen in the table below. The utility of the section modulus is that it characterizes the bending resistance of a cross section in a single term. This engineering data is often used in the design of structural beams or structural flexural members.

For asymmetrical sections two values are found. Z max and z min. Moment of inertia section modulus radii of gyration equations t sections.

Section modulus radii of gyration equations w and s profiles. Section properties case 27 calculator. Calculate moment of inertia for a rectangle section find cross sectional area section modulus and radius of gyration for a rectangle shape beam.

It is often reported using y c where c is the distance from the neutral axis to the most extreme fibre as seen in the table below. Where i moment of inertia y distance from centroid to top or bottom edge of the rectangle. Zx b h 2 h 4 b h 2 h 4 bh2 4.

The elastic section modulus is defined as s i y where i is the second moment of area or area moment of inertia not to be confused with moment of inertia and y is the distance from the neutral axis to any given fibre. The links below on the left are section modulus calculators that will calculate the section area moment of inertia properties of common shapes used for fabricating metal into various shapes such as squares rounds half rounds triangles rectangles trapezoids hexagons octagons and more.

This engineering calculator will determine the section modulus for the given cross section. The elastic section modulus is defined as s i y where i is the second moment of area or moment of inertia and y is the distance from the neutral axis to any given fiber. Moment of inertia section modulus radii of gyration equations t.
