Question: The 10-kg circular disk spins about its axle with a constant angular velocity of = 15 rad/s. Simultaneously, arm OB and shaft OA rotate

The 10-kg circular disk spins about its axle with a constant angular velocity of ω₁ = 15 rad/s. Simultaneously, arm OB and shaft OA rotate about their axes with constant angular velocities of ω₂ = 0 and ω₃ = 6 rad/s, respectively. Determine the angular momentum of the disk about point O, and its kinetic energy.
