A flywheel of mass 140 kg and radius of gyration 3.5 m is rotated with a speed of 240 rpm. Find the torque required to stop it in 3.5 rotations ?

Explanation

To find the torque required to stop a flywheel in a given number of rotations, we can follow these steps:

### Step 1: Convert the speed from RPM to radians per second
The initial speed of the flywheel is given as 240 RPM. We need to convert this to radians per second using the formula:
\[ \omega_0 = 2\pi \times \frac{n}{60} \]
where \( n \) is the speed in RPM.
