Calculating moment of inertia for rotating bar around end

The video tutorial explains how to calculate the moment of inertia for a rigid bar rotating around one of its endpoints. It introduces the concept of moment of inertia, discusses formulas for discrete and continuous bodies, and sets up the problem using axes and elements. The tutorial then calculates the density and mass of an element, performs integration with limits, and simplifies the result to derive the moment of inertia formula for a bar rotating around one end.
