What does a high mechanical advantage in a pulley system indicate?

A high mechanical advantage in a pulley system is a significant benefit because it allows heavy loads to be lifted with less applied force. This is achieved by using multiple pulleys in a configuration that effectively spreads the load across several sections of rope or cable, which reduces the force needed to lift the object.

When the mechanical advantage is high, each segment of rope supports a portion of the load, meaning that the user does not have to exert as much effort to lift the object to the desired height. This feature makes tasks involving heavy lifting more manageable, improving overall ease of use, safety, and efficiency in lifting operations. Thus, the correct answer highlights the practical advantage of high mechanical advantage in reducing the force required for lifting heavy loads.
