Step 1
Given:
- The initial angular velocity of disk B is ω0.
- The mass of the disk A is mA.
- The mass of the disk B is mB.
- The radius of disk A and B are rA and rB
Let the final angular velocity at disk A and B be ωA and ωB and assume a point C between A and B.
Due to zero slippage, the velocity at point C is
The expression of moment of inertia for disk A and B is,
Here IA and IB are the moment of inertia due to A and B.
The first moment about disk A is zero as it’s at rest.
