Beam Section Modulus

Calculate beam EI and section modulus for a circular pipe.

The section modulus is equal to the moment of inertia divided by the length from the centroid to the outer fiber (the outside radius). For combined stress calculations, the section modulus can be calculated using the length from the centroid to the pipe mid wall.
