What should be done to determine the mechanical advantage of a compound machine?

To determine the mechanical advantage (MA) of a compound machine, the appropriate method involves multiplying the mechanical advantages of the individual simple machines that comprise it. Each simple machine, such as a lever, pulley, or inclined plane, will have its own specific mechanical advantage based on its design and function.

When a compound machine is assembled from multiple simple machines, the overall efficiency and effectiveness in performing work are captured by the combined mechanical advantage of the individual components. By multiplying the MAs, you're effectively considering how each segment enhances the ability to perform a task, thus providing a comprehensive view of the machine's capability.

For instance, if a compound machine is made up of a pulley system and a lever, each with a defined MA, you would multiply those values to find the total mechanical advantage. This method reflects the cumulative benefit of using multiple simple machines in tandem for greater efficiency.
