The 20kg disk is spinning about its centre at omegazangular

The 20kg disk is spinning about its centre at omega-z(angular velocity about z)=20rad/s while the supporting axle is rotating at omega-y(angular velocity about y)=6rad/s.Determine the magnitude of moment caused by the force reactions which the pin exerts on the disk. Also please explain steps.

Solution

The magnitude of moments caused by the force reaction which the pub exerts on disk is 67n-m.

The way for the problem is start with the free body diagram.
