Question

The 5-kg disk and hub A have a radius of gyration of 85 mm about the z-axis and spin at the rate p = 1250 rev/min. Simultaneously, the assembly rotates about the vertical z-axis at the rate Ω = 400 rev/min. Calculate the gyroscopic moment M exerted on the shaft at C by the disk and the bending moment MO in the shaft at O. Neglect the mass of the shaft but otherwise account for all forces acting on it.

Step 1

Given: Mass moment of inertia of the disk, I = 0.0361 kgm^2 Mass moment of inertia about not I not, I_0 = 0.018 kgm^2 Spin rate, p = 41.9 rad/s Rotation rate, Omega = 41.9 rad/s Using the formula for gyroscopic moment: M = I * Omega * sin(theta) * Omega * Show more…
