moment of inertia of area T bar

The video tutorial explains how to calculate the moment of inertia of a T-bar using the parallel axis theorem. It begins with an introduction to the problem, followed by a review of the parallel axis theorem. The T-bar is then split into two parts, and the moment of inertia for each part is calculated separately. The final result is obtained by summing the individual moments of inertia.
