A relatively thin disc with uniformly distributed mass is mounted on a shaft which rotates at 1000 RPM. To conduct a test, two extra masses are added to the disc at the positions shown in Figure Q10. Masses A and B introduce known unbalances of 2 kgmm and 4 kgmm, respectively. Determine the angular location of the correction mass measured from y-axis in the clockwise direction and the centrifugal force that it needs to produce in order to balance the system. ул 30° B 70° X 111 TTT Z

Question
A relatively thin disc with uniformly distributed mass is mounted on a
shaft which rotates at 1000 RPM. To conduct a test, two extra masses
are added to the disc at the positions shown in Figure Q10. Masses A
and B introduce known unbalances of 2 kgmm and 4 kgmm,
respectively. Determine the angular location of the correction mass
measured from y-axis in the clockwise direction and the centrifugal force
that it needs to produce in order to balance the system.
