Explanation:
From the question we are told that
The radius of the grinding wheel is 
The tangential force is 
The angular acceleration is 
The torque experienced by the wheel is mathematically represented as

Where I is the moment of inertia
The torque experienced by the wheel can also be mathematically represented as

substituting values


So


So

This moment of inertia can be mathematically evaluated as

substituting values

=>
