A forum user seeks assistance in drawing a velocity polygon for a press mechanism, specifically focusing on the point of contact between two gears, referred to as point A. The user initially misidentified points in their diagram but later clarified that point A acts as a swivel hinge, which they equate to point O2. Responses indicate confusion about the swivel concept and emphasize that the larger gear rotates clockwise, affecting the velocity vector of joint B. The discussion concludes with the user acknowledging the need to consult their professor for further clarification, as the assignment is intended to be a conceptual representation rather than a numerical analysis. The exchange highlights the importance of accurately representing mechanical relationships in kinematic diagrams.
