SUMMARY
The forum discussion centers on calculating the center of mass (COM) for a uniform thin wire shaped as a half-circle and two straight lines. The user, Femme_physics, initially arrives at a different result for the Y-coordinate (Yc) compared to the solution manual, due to a misunderstanding of the geometry involved. After clarifying that the shape consists solely of lines without defined areas, Femme_physics successfully recalculates Yc. The discussion also highlights the importance of correctly choosing the origin for the X-coordinate (Xc) calculation, revealing discrepancies in the solution manual's approach.
