The 5-kg disk and hub A have a radius of gyration of 85 mm about the -axis and spin at the rate P = 1250 rev/min. Simultaneously, the assembly rotates about the vertical z-axis at the rate Ω = rev/min. Calculate the gyroscopic moment M exerted on the shaft at C by the disk and the bending moment M₀ in the shaft at O. Neglect the mass of the shaft but otherwise account for all forces acting on it.
