A gyroscope consists of a uniform disc of mass radius M= 1 kg and radius R= 0.3 m . The disc spins with an angular speed ω= 400 rad⋅s-1 as shown in the figure below. The gyroscope precesses, with its axle at an angle 30∘ below the horizontal (see figure). The gyroscope is pivoted about a point d= 0.4 m from the center of the disc. What is the magnitude of the precessional angular velocity Ω (in radians/sec)?
Ω=????
please help!!

it didn't work :(
maybe you made a mistake.. it works
NO it doesn't work because :
Omega=(m*g*d)/(I*angular speed)
without the '2'
