Finding angular velocity of a rotating bar

The video tutorial explains how to find the angular velocity of a swinging bar using energy methods. It begins with an introduction to the problem, followed by deriving and simplifying the energy equation. A free body diagram is used to analyze forces, and the equation is further simplified. The tutorial considers rotation around the center of mass and concludes with final calculations to determine the angular velocity.
