Belt problem itself. In the pulley problem the length of the belt is where "r" represents the radius of the larger pulley, "r" represents the radius of the smaller one, and: The belt problem is used in the design of aeroplanes, bicycle gearing, cars, and other items with pulleys or belts that cross each other. The pulley problem is also used in the design of conveyor belts found in airport luggage belts and automated factory lines. Belt problem The belt problem is a mathematics problem which requires finding the length of a crossed belt that connects two circular pulleys with radius "r"
