Webmoment of inertia is the same about all of them. In its inertial properties, the body behaves like a circular cylinder. The tensor of inertia will take diﬀerent forms when expressed in diﬀerent axes. When the axes are such that the tensor of inertia is diagonal, then these axes are called the principal axes of inertia.
