Because pressure increases as you go down in the liquid, the “pressure prism” is thicker towards the bottom, and therefore, the center of pressure CP is located below the centroid C. individual spots to calculate local slopes, (b) formation of the wavefront shape from local slope measurements. The plastic neutral axis is defined as the axis that splits the cross section in such a way that the compression force from the compression area is equal to the tension force from the tension area. Moment of Inertia In classical mechanics, moment of inertia, also called mass moment of inertia, rotational inertia, polar moment of inertia of mass, or the angular mass, (SI units kg m 2) is a measure of an object's resistance to changes to its rotation. The masses can either be positive or negative. The centroid divides each of the medians in the ratio 2:1, which is to say it is located ⅓ of the perpendicular distance between each side and the opposing point (see figures at right).
