Class 11PhysicsSystem of Particles and Rotational MotionRelation between Torque and Angular acceleration and it's Application
Difficult$A$ wheel having a moment of inertia of $2 \, kg \cdot m^2$ about its vertical axis rotates at the rate of $60 \, rpm$ about the axis. The torque required to stop the wheel's rotation in one minute would be
- A$\frac{\pi}{12} \, N \cdot m$
- B$\frac{\pi}{15} \, N \cdot m$
- C$\frac{\pi}{18} \, N \cdot m$
- D$\frac{2\pi}{15} \, N \cdot m$

View SolutionTwo small balls with masses $m$ and $2m$ are attached to both ends of a rigid rod of length $d$ and negligible mass. If the angular momentum of this system is $L$ about an axis $(A)$ passing through its centre of mass and perpendicular to the rod, then the angular velocity of the system about $A$ is:
$A$ constant torque of $31.4 \, N \cdot m$ is applied to a pivoted wheel. If the angular acceleration of the wheel is $4\pi \, rad/s^2$,then the moment of inertia of the wheel is ....... $kg \cdot m^2$. (in $.5$)
