Relative Motion with rotating reference axes Example (part 1)

The video tutorial explains how to solve a relative motion problem involving a pin constrained to move within a slotted link. The problem is set up with given parameters, including angular velocity and dimensions. The instructor explains the velocity equation and reference frames, followed by a conceptual understanding of the motion. The video then analyzes velocity components and solves for unknowns like angular velocity and VREL. Finally, the tutorial calculates the final velocity vector of pin A.
