Inertia = \frac{a^4 - b^4}{12} \quad

Modulus = \frac{a^4 - b^4}{6a} \quad

Radius = \sqrt{\frac{a^2 + b^2}{12}} \quad

Area = a^2 - b^2

These formulas are used to calculate different properties of a cross-sectional shape that is assumed to be an ellipse with major axis a and minor axis b.

**Inertia**– calculates the moment of inertia of the shape about its centroid. Moment of inertia is a measure of an object’s resistance to rotational motion.**Modulus**– calculates the section modulus of the shape. Section modulus is a measure of a shape’s resistance to bending.**Radius**– calculates the radius of gyration of the shape about its centroid. The radius of gyration is a measure of how far the mass of an object is distributed from its axis of rotation.**Area**– calculates the area of the shape.

Calculating the section properties of a square tube at its center is made simpler with the help of a free online engineering calculator.
