A horizontal plane supports a plank with a bar of mass m placed on it and attached by a light elastic non-deformed cord of length l0 to a point O. The coefficient of friction between the bar and the plank is equal to m. The plank is slowly shifted to the right until the bar Two identical blocks A and B
