Task id15169

An “oh-yo” toy (fig.) with a thread wound around a rod can roll along the table. In which direction will it roll back if the thread is pulled horizontally by force F1? What happens if a force F2 is applied to the thread, directed in such a way that the continuation of the line of action of the force passes through the points of contact of the “oh-yo” with the table? What happens if the thread tension by force F3 is directed vertically upward?
