Torque and Angular Momentum

When there is no external torque acting on a rotating body, which of the following quantities can change ? (i) Angular acceleration (ii) Angular momentum (iii) Angular speed.

If a wheel has mass 70 kg and radius of gyration 1 m, then the torque required an angular 1 m, then the torque required an angular acceleration of "2 rev"//s^(2) will be

Two identical masses are connected to a horizontal thin massless rod as shown in the figure. When their distance from the pivot is x , a torque produces an angular acceleration alpha_(1) . If the masses are now repositioned so that they are at distance 2x each from the pivot, the same torque will produce an angular acceleration alpha_(2) such that ,

The moment of inertia of a body is 2.5 kg m^(2) . Calculate the torque required to produce an angular acceleration of 18 rad s^(-2) in the body.

A flywheel revolves at 100 rev/min, a torque is applied to the flywheel for 10 s If the torque increases the speed to 200 rev/min, then the angular acceleration of the flywheel will be

On the application of a constant torque , a wheel is turned from rest through 400 radians in 10 s. The angular acceleration is :

A torque of magnitude 2000 Nm acting on a body produces an angular acceleration of 20" rad/s"^(2) , The moment of inertia of the body is
