A machine part consists of a thin 0.6 m long bar with small 1 kg masses fastened by screws to its ends. The screws can support a maximum force of 65 N without pulling out. This bar rotates about an axis perpendicular to it at its center. As the bar is turning at a constant rate on a horizontal frictionless surface, what maximum speed the masses can have without pulling out the screws?
