What is the impact of increasing the load on a pulley system with a constant force applied?

• A. The mechanical advantage increases
• B. The mechanical advantage decreases
• C. The system cannot lift the load
• D. The speed decreases

Answer: (C)

When a constant force is applied to a pulley system, increasing the load can lead to limitations on the system's ability to lift that load. A pulley system is designed to make lifting easier by redistributing the force required to move the load. However, if the load exceeds the capacity of the system to lift it, the force applied will not be sufficient to overcome the weight of the load. Thus, the system becomes incapable of lifting, resulting in a scenario where it cannot effectively move the load upward. As for the other choices, a constant force does not alter the mechanical advantage; rather, it is determined by the configuration of the pulley system itself. The speed of the load’s movement also depends on the applied force in relation to the load; if the system cannot lift the load, the speed becomes irrelevant since there is no movement happening at all.
