What is the ratio of the load to the effort in a simple machine called?

The ratio of the load to the effort in a simple machine is referred to as the Actual Mechanical Advantage. This concept is critical in understanding how effectively a machine can amplify an input force. In essence, it indicates how much load the machine can lift compared to the effort applied.

For a well-designed machine, the Actual Mechanical Advantage will provide insight into its performance, showing the relationship between the input force (effort) and the output force (load). This term is used to assess the effectiveness of various types of simple machines, from levers to pulleys, and informs users about the potential benefits of using mechanical advantage to facilitate labor.

Velocity ratio, on the other hand, relates to the distance moved by the effort compared to the distance moved by the load, while efficiency is a measurement of how well input energy is converted into useful work output. Power quantifies the rate of doing work or the rate of energy transfer. Understanding these distinctions is vital for effectively applying mechanical principles in practical scenarios.
