SUMMARY
The forum discussion centers on designing a yo-yo capable of achieving maximum height from a 30m drop, utilizing a 10mm thick elastic rope. Key factors include minimizing energy loss during the transition from downward to upward motion, maximizing angular momentum, and optimizing the yo-yo's geometry. Participants suggest using spoked hubs for increased moment of inertia, incorporating ball bearings to reduce friction, and considering a conical axis design to guide the rope effectively. The ideal yo-yo should weigh close to the maximum limit of 10kg while fitting within a 1.2m cube.
