In case of principal axes of a section
WebFrequently in civil engineering construction beam sections do not possess any axes of symmetry. Typical examples are shown in Fig. 9.21where the angle section has legs of unequal length and the Z-section possesses anti- or skew symmetry about a horizontal axis through its centroid, but not symmetry. WebIn this case, the other two principal axes can be determined as follows. Suppose that the -axis is known to be a principal axes (at the origin) in some coordinate system. It follows that the two products of inertia and are zero [otherwise, would not be an eigenvector in Equation ( …

Speaking after an urgently convened ... WebAny rigid body has three principal axes, which are mutually orthogonal, or can be chosen to be so. If a body has an axis of symmetry then rotations about that axis will be dynamically balanced; in other words that axis is a principal axis. Hence we can use the symmetries of a body to recognise principal axes:
