(b)

Answer to Problem 34P
The value is
Explanation of Solution
Given information:
A grinding wheel is a uniform cylinder with a radius or
Formula used:
Here,
Calculation:
As the cylinder slows down, let us calculate the negative
Initial rotational frequency
Hence initial angular velocity
Time taken for wheel to come to rest,
Hence if
If the cylinder has to accelerate from rest to
Hence torque that needs to be applied is
Conclusion:
The value is
