Q10: A disc whose moment of inertia is worth 1.27 kg.m? rotates with an angular velocity of 824rpm around a vertical axis of negligible moment of inertia. A second disc, at a moment of inertia4.85 kg.m?, initially at rest, is coupled sharply to the axis. What will be the angular velocity ofcombining the two discs rotating together with the same angular velocity?

Solution: The moment of inertia of the two discs is 1.27 kgm2 and 4.85 kg m2 respectively. The lower…
