Angular Velocity and Relative Motion

The video tutorial covers a relative velocity problem involving a rod sliding horizontally. It explains the use of the relative velocity method to determine the angular velocity of a bar and a disc. The instructor emphasizes understanding the process rather than memorizing figures. Key steps include setting up equations, using cross products, and solving for unknowns. The tutorial concludes with final calculations and a summary of the problem-solving approach.
