The thin plate rotates with a constant angular velocity ω = 200 rad / s. Its center of gravity is on the axis of rotation, and the centrifugal moment of inertia relative to the axes in the plane of the plate is Ixz = -2.5 · 10-3 kg · m2. Determine the principal moment of the inertia forces relative to the Oy axis. (Answer -100)
