A grindstone of moment of inertia 6 kg m^(2) is found to have a speed of 150 rpm, 10 sec . After starting from rest. Torque applied is

A grindstone has moment of inertia 0.5kgm^2 .What constant torque should be applied so that it attains an angular velocity of 120 rpm in 8sec .

A grindstone has moment of inertia 0.5kgm^2 .What constant torque should be applied so that it attains an angular velocity of 120 rpm in 8sec . In the above case what is the rate at which work is done at the end of 8sec .

A constant torque of 200 Nm turns a wheel of moment of inertia 50 kg m^(2) about an axis through its centre. The angualr velocity 2 sec after staring form rest (in rad/sec) would be :

A solid sphere of radius 20 cm and mass 25 kg rotates about an axis through its centre. Calculate its moment of inertia. If its angular velocity the torque applied changes from 2 rad s^-1 to 12 omega rad s^-1 in 5 sec, calculate the torque applied.
