relative motion basic example

The video tutorial covers a relative motion problem involving a bar constrained by rollers. The problem requires finding the velocity of point B and the angular velocity of the bar. The tutorial explains the direction of B's velocity using common sense and explores the velocity of A relative to B through circular motion concepts. It uses vector analysis and geometry to understand the motion and connects velocity vectors mathematically. The tutorial concludes by solving for the magnitudes of velocities and the angular velocity using trigonometry.
