The thin uniform disk of mass m = 1-kg and radius R = 0.1m spins about the bent shaft OG with the angular speed w2 = 20 rad/s. At the same time, the shaft rotates about the z-axis with the angular speed 001 = 10 rad/s. The angle between the bent portion of the shaft and the z-axis is ẞ = 35°. The mass of the shaft is negligible compared to the mass of the disk. a. Find the angular momentum of the disk with respect to point G, based on the axis orientation as shown.

I have Euler parameters that describe the orientation of U relative to N, e = -1/sqrt(3)*n1, e4 = sqrt(2/3). After using euler parameter rule of successive rotations, I get euler parameters that describe the orientation of U relative to Q, e = -0.4082*n1 - 0.4082*n2 - 0.5774*n3.
