An analysis yielding the respective forces acting at any point of any member, or part of a member, of a mechanism, obtained by using relationships for dynamic equilibrium in a plane rigid body subject to external forces within this plane and to internal forces due to its motion in this plane.
Answer:
i.e.

Explanation:
Given:
angular speed,
mass of the disk, 
radius of the disk, 
mass of the chunk, 
radius of the chunk, 
We know that the angular momentum is given by:

and moment of inertia for a disc:

According to the conservation of angular momentum, the final angular momentum is equal to the initial angular momentum.
