E0042 tire conicity & ply steer part 15 – moment of area#3 : triangle and circle - EulSeoggy Ko

The second and product moment of area can be calculated by direct integration, and if the second and moment of section passing through the centroid are known, it can also be calculated by the parallel axis theorem. The parallel axis theorem states that we need to apply a value for an axis that is parallel to the reference axis and passes through the centroid as a moment value known to us. If we use values for axes that do not pass through the centroid, the parallel axis theorem does not hold. In various types of triangles, the second moment of area is the same for all triangles whose bases coincide with the horizontal axis, the lengths of the bases are equal to each other, and the lengths of the heights are equal to each other. Polar moment of area is defined as antiderivative of radius r squared with respect to the area. Pola moment of area can also be obtained using the parallel axis theorem. polar moment of area equals the sum of second moments of area to the corresponding axes.
