1.
A rotating disk is connected with two arms AD and DB which are rotating with the rate of 0.2 rad/s^2 and -0.3 rad/s^2 respectively about X or x' axis. Disk itself is rotating about small z axis with the rate of 1500 rpm.

AD and DB is rotating in ZY plane. Small z co-insides with DB arm. X and x are parallel. Length of the AD and DB is given.

Now how I should approach this problem to find the total angular velocity and acceleration of the disk with respect to the inertial co-ordinate system XYZ2. 3. So far what I think of the solution:
Total Angular Acceleration, w:
W = w(of the rotating disk) + w(B/D) + w(D/A)
Velocity V(B/A) = (V)Rel + (W * ( Position Vector R(B/A) ) )

Total Angular Acceleration, w:
W = w(of the rotating disk) + w(B/D) + w(D/A)

Is that what you meant? w is more normally used (substituting for Greek ω) to mean angular velocity. α is used for angular acceleration.

Velocity V(B/A) = (V)Rel + (W * ( Position Vector R(B/A) ) )

That reads more like you are discussing linear velocity (referring to points B, A), not angular velocity.
