How does a pulley make it easier to load cargo onto a cargo ship?

A pulley simplifies the process of loading cargo onto a cargo ship by allowing for the efficient lifting and movement of heavy items with minimal effort. It changes the direction of the force applied, enabling workers to pull down on a rope to lift the load upward. Additionally, using a system of multiple pulleys can distribute the weight and reduce the amount of force needed, making it easier to manage heavy cargo. This mechanical advantage enhances safety and efficiency during loading operations.
