Grinding Wheel
What is angular momentum of a 2.6kg uniform cylindrical grinding wheel of radius 18cm when rotating at 1200rpm?
What magnitude of torque is required to stop it in 6.0 s?
NOW THE MASS OF THE WHEEL IS 2.6Kg;
raduis of the wheel is 18cm = 0.18m;
Now the velocity of the wheel=1200rpm=1200/60rps=20rps;
therefore the angular momentum=2.6*0.18*20=9.36kgm^2.s^-1.
