Unformatted text preview: ½ MR^2. M is the mass of the disk and R is the radius of the disk. Measurements: Disk 1: 1353 g Disk 2: 469 g Pulley mass: 90 g Radius: 8 cm 2. The bottom steel disk will be stationary on the base plate; the top steel disk will “float” on the lower one. The torque is applied by the hanging mass, and using the LabPro interface, we will calculate the inertia of the system. 3. Plug the phone jack with the yellow band into Port 1 of the ULI. 4. After opening the air supply, begin collecting data after releasing the weight, allowing the disk to spin freely. 5. Analyze data. Data analysis: Using the previous calculations, the calculated inertia of the disk and the actual inertias were found… Calc. Inertia Actual Inertia Percent Error Disk 1 4.3296 kg m 2 4.5610 kg m 2 5.0% Disk 2 1.5008 kg m 2 1.6531 kg m 2 9.2% Conclusion: Using derived calculations, we can determine the expected inertia of a uniform-mass cylindrical object with relatively low error....
