Question7<br />
The unbalanced 25 kg flywheel shown in Fig. Q7 has a radius <strong>of</strong> gyration <strong>of</strong> 0.18 m<br />
about an axis passing through its mass centre G. If it has a clockwise angular velo<strong>city</strong> <strong>of</strong><br />
8 rad/s at the instant shown, draw the free body diagram and mass <strong>ac</strong>celeration diagram.<br />
