Section Modulus Of A Circle

A circle is a shape whose distance from the center to any point at its outline is the same.

Section modulus of a circle. Equations for the section moduli of common shapes are given below. J i polar moment of inertia in 4 or mm 4. S frac pi r 4 4r rightarrow s frac pi r 3 4.

Enter the radius of a circle and find its section modulus. Online hollow circle annulus property calculator. Z elastic section modulus in 3 or mm 3.

Therefore application of the above formula to a circular cross section provides the following expression for the elastic modulus around any centroidal axis. K radius of gyration in or mm. Section modulus is a geometric property for a given cross section used in the design of beams or flexural members.

I second moment of area in 4 or mm 4. Z elastic section modulus in 3 or mm 3. J torsional constant in 4 or mm 4.

Other geometric properties used in design include area for tension and shear radius of gyration for compression and moment of inertia and polar moment of inertia for stiffness. Any relationship between these properties is highly dependent on the shape in question.

C distance to centroid in or mm. Using the structural engineering calculator located at the top of the page simply click on the the show hide calculator button the following properties can be calculated. Calculate the area of a hollow.
