Relative motion problem

The video tutorial addresses a complex relative motion problem involving a mechanical assembly. It begins by setting up the problem and identifying the need to find the angular velocity of link BC and the velocity of slider C. The instructor uses geometry and trigonometry to solve for angles within the assembly, then applies relative motion formulas to determine the velocities of various components. The tutorial emphasizes understanding the direction and magnitude of velocities and concludes with calculating the angular velocity of link BC using trigonometric principles.
