Flattening factor for tube

WebFirst, let’s revisit our tube geometry below. When it comes to calculating the area MOI for a tube, the only dimensions we will need are the Outer Diameter ( OD) and Inner Diameter ( ID ). The formula for a tube’s area MOI is shown below: Ix=Iy= π (OD4-ID4)64. Where: Ix= Area MOI about the x axis. Flattening is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution (spheroid) respectively. Other terms used are ellipticity, or oblateness. The usual notation for flattening is f and its definition in terms of the semi-axes of the resulting ellipse or ellipsoid is The compression factor is in each case; for the ellipse, this is also its aspect ratio
