Calculate the mass and moment of the flywheel using basic principles, i.e. theoretically. The specific gravity of steel is 7.8. 5. Calculate three sets of the linear and angular velocities and accelerations using the results from the three experiments. Assuming that no slip occurs, the angular and linear velocities and accelerations are related. 6. Calculate the frictional force of the bearing. You will need to read Appendix 2 in order to perform this calculation. 7. By applying the equations of motion to the results from the experiments and the accelerations calculated in step 5, calculate the moment of inertia of the flywheel. Remember to include the effect of bearing friction. 8. By applying the energy method to the results from the experiments and the velocities calculated in step 6, obtain the moment of inertia of the flywheel. Remember to include the effect of bearing friction. 9. Compare the moments of inertia from all 3 experiments and the theoretical value in the form of a table as below and comment on your findings: Theoretical Moment of Experiment Izz using equations Inertia of Flywheel No 1 2 3 of motion Izz using the energy method Flywheel Shaft radius r Shaft radius r WI W2 (a) W3 Radius Cord m mass radius R W1=7.5 cm Figure 3: Dimensions of flywheel.
