Graph of angular acceleration versus applied torque for the flywheel.
Graph of angular acceleration versus applied torque for the flywheel.
A student performs an experiment to determine the rotational inertia and the frictional torque of a flywheel mounted on a fixed axle. The student exerts various positive applied torques \(\tau_{\text{applied}}\) to the flywheel and measures the resulting angular acceleration \(\alpha\). A linear fit to the experimental data is plotted below.

Which of the following statements correctly relates the features of the graph to the physical properties of the flywheel system?
