Graphing the Rotational Inertia of an Irregular Shape

The video tutorial explains how to measure the rotational inertia of irregular shapes using a pulley system with different radii. It covers drawing free body diagrams, calculating torque, and setting up a graph to determine rotational inertia. The process involves collecting data, calculating angular acceleration, and plotting results to find the best fit line. The tutorial concludes with confirming the units of the calculated rotational inertia.
