Please use SI units only for the following problem. Assume that you have generated a graph of applied torque due to tension vs. angular acceleration for a disk/hub combination similar to that used in the Rotational Motion Jab. The slope of the graph Is 0.0065730 and the y-intercept of the graph is 0.0004680. What is the experimental frictional torque of the system? What is the experimental moment of Inertia of the system? If the radius of the aluminum hub is 0.0150 m and its mass Is 0.0889 kg, and the radius of the disk Is 0.125 m and the mass of the disk is 0.8000 kg, then what is the theoretical moment of inertia of the combined disk/hub system? What is % difference of the experimental value of I compared to the theoretical value of I of the hub/disk combination?
