The construction of the Brooklyn Bridge utilized a variety of levers and pulleys to facilitate the lifting and positioning of heavy materials. Large cranes equipped with pulleys were employed to hoist steel cables and sections of the bridge into place. Additionally, workers used lever systems to help manipulate and secure the massive stone blocks that formed the bridge's towers. These simple machines were crucial in overcoming the challenges of building such a monumental structure in the late 19th century.
