In simple machines, what is the term for the ratio of load to effort?

The correct term for the ratio of load to effort in simple machines is known as Actual Mechanical Advantage (AMA). This concept is essential in understanding how effectively a machine converts input force (effort) into output force (load). AMA is calculated by dividing the load (the force exerted by the machine) by the effort (the force applied to the machine).

By taking this ratio, students can see how much the machine improves the force applied. A higher AMA indicates that the machine is more effective in lifting loads with less effort. This concept is foundational in power engineering and helps in assessing the performance of various machines.

Mechanical Efficiency relates to how well a machine converts the input work to output work, factoring in energy losses typically due to friction. Velocity Ratio describes the relationship between the distances moved by the effort and load but does not directly address the force ratio. Load Factor pertains to the ratio of actual load to maximum load but does not describe the relationship between load and effort. Hence, Actual Mechanical Advantage is the most accurate term in this context.
